+
+/// Provides waitable timer functionality.
+/**
+ * The basic_deadline_timer class template provides the ability to perform a
+ * blocking or asynchronous wait for a timer to expire.
+ *
+ * A deadline timer is always in one of two states: "expired" or "not expired".
+ * If the wait() or async_wait() function is called on an expired timer, the
+ * wait operation will complete immediately.
+ *
+ * Most applications will use the asio::deadline_timer typedef.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Examples
+ * Performing a blocking wait:
+ * @code
+ * // Construct a timer without setting an expiry time.
+ * asio::deadline_timer timer(my_context);
+ *
+ * // Set an expiry time relative to now.
+ * timer.expires_from_now(boost::posix_time::seconds(5));
+ *
+ * // Wait for the timer to expire.
+ * timer.wait();
+ * @endcode
+ *
+ * @par 
+ * Performing an asynchronous wait:
+ * @code
+ * void handler(const asio::error_code& error)
+ * {
+ *   if (!error)
+ *   {
+ *     // Timer expired.
+ *   }
+ * }
+ *
+ * ...
+ *
+ * // Construct a timer with an absolute expiry time.
+ * asio::deadline_timer timer(my_context,
+ *     boost::posix_time::time_from_string("2005-12-07 23:59:59.000"));
+ *
+ * // Start an asynchronous wait.
+ * timer.async_wait(handler);
+ * @endcode
+ *
+ * @par Changing an active deadline_timer's expiry time
+ *
+ * Changing the expiry time of a timer while there are pending asynchronous
+ * waits causes those wait operations to be cancelled. To ensure that the action
+ * associated with the timer is performed only once, use something like this:
+ * used:
+ *
+ * @code
+ * void on_some_event()
+ * {
+ *   if (my_timer.expires_from_now(seconds(5)) > 0)
+ *   {
+ *     // We managed to cancel the timer. Start new asynchronous wait.
+ *     my_timer.async_wait(on_timeout);
+ *   }
+ *   else
+ *   {
+ *     // Too late, timer has already expired!
+ *   }
+ * }
+ *
+ * void on_timeout(const asio::error_code& e)
+ * {
+ *   if (e != asio::error::operation_aborted)
+ *   {
+ *     // Timer was not cancelled, take necessary action.
+ *   }
+ * }
+ * @endcode
+ *
+ * @li The asio::basic_deadline_timer::expires_from_now() function
+ * cancels any pending asynchronous waits, and returns the number of
+ * asynchronous waits that were cancelled. If it returns 0 then you were too
+ * late and the wait handler has already been executed, or will soon be
+ * executed. If it returns 1 then the wait handler was successfully cancelled.
+ *
+ * @li If a wait handler is cancelled, the asio::error_code passed to
+ * it contains the value asio::error::operation_aborted.

+/// Provides signal functionality.
+/**
+ * The basic_signal_set class provides the ability to perform an asynchronous
+ * wait for one or more signals to occur.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Example
+ * Performing an asynchronous wait:
+ * @code
+ * void handler(
+ *     const asio::error_code& error,
+ *     int signal_number)
+ * {
+ *   if (!error)
+ *   {
+ *     // A signal occurred.
+ *   }
+ * }
+ *
+ * ...
+ *
+ * // Construct a signal set registered for process termination.
+ * asio::signal_set signals(my_context, SIGINT, SIGTERM);
+ *
+ * // Start an asynchronous wait for one of the signals to occur.
+ * signals.async_wait(handler);
+ * @endcode
+ *
+ * @par Queueing of signal notifications
+ *
+ * If a signal is registered with a signal_set, and the signal occurs when
+ * there are no waiting handlers, then the signal notification is queued. The
+ * next async_wait operation on that signal_set will dequeue the notification.
+ * If multiple notifications are queued, subsequent async_wait operations
+ * dequeue them one at a time. Signal notifications are dequeued in order of
+ * ascending signal number.
+ *
+ * If a signal number is removed from a signal_set (using the @c remove or @c
+ * erase member functions) then any queued notifications for that signal are
+ * discarded.
+ *
+ * @par Multiple registration of signals
+ *
+ * The same signal number may be registered with different signal_set objects.
+ * When the signal occurs, one handler is called for each signal_set object.
+ *
+ * Note that multiple registration only works for signals that are registered
+ * using Asio. The application must not also register a signal handler using
+ * functions such as @c signal() or @c sigaction().
+ *
+ * @par Signal masking on POSIX platforms
+ *
+ * POSIX allows signals to be blocked using functions such as @c sigprocmask()
+ * and @c pthread_sigmask(). For signals to be delivered, programs must ensure
+ * that any signals registered using signal_set objects are unblocked in at
+ * least one thread.

+/// Automatically resizable buffer class based on std::streambuf.
+/**
+ * The @c basic_streambuf class is derived from @c std::streambuf to associate
+ * the streambuf's input and output sequences with one or more character
+ * arrays. These character arrays are internal to the @c basic_streambuf
+ * object, but direct access to the array elements is provided to permit them
+ * to be used efficiently with I/O operations. Characters written to the output
+ * sequence of a @c basic_streambuf object are appended to the input sequence
+ * of the same object.
+ *
+ * The @c basic_streambuf class's public interface is intended to permit the
+ * following implementation strategies:
+ *
+ * @li A single contiguous character array, which is reallocated as necessary
+ * to accommodate changes in the size of the character sequence. This is the
+ * implementation approach currently used in Asio.
+ *
+ * @li A sequence of one or more character arrays, where each array is of the
+ * same size. Additional character array objects are appended to the sequence
+ * to accommodate changes in the size of the character sequence.
+ *
+ * @li A sequence of one or more character arrays of varying sizes. Additional
+ * character array objects are appended to the sequence to accommodate changes
+ * in the size of the character sequence.
+ *
+ * The constructor for basic_streambuf accepts a @c size_t argument specifying
+ * the maximum of the sum of the sizes of the input sequence and output
+ * sequence. During the lifetime of the @c basic_streambuf object, the following
+ * invariant holds:
+ * @code size() <= max_size()@endcode
+ * Any member function that would, if successful, cause the invariant to be
+ * violated shall throw an exception of class @c std::length_error.
+ *
+ * The constructor for @c basic_streambuf takes an Allocator argument. A copy
+ * of this argument is used for any memory allocation performed, by the
+ * constructor and by all member functions, during the lifetime of each @c
+ * basic_streambuf object.
+ *
+ * @par Examples
+ * Writing directly from an streambuf to a socket:
+ * @code
+ * asio::streambuf b;
+ * std::ostream os(&b);
+ * os << "Hello, World!\n";
+ *
+ * // try sending some data in input sequence
+ * size_t n = sock.send(b.data());
+ *
+ * b.consume(n); // sent data is removed from input sequence
+ * @endcode
+ *
+ * Reading from a socket directly into a streambuf:
+ * @code
+ * asio::streambuf b;
+ *
+ * // reserve 512 bytes in output sequence
+ * asio::streambuf::mutable_buffers_type bufs = b.prepare(512);
+ *
+ * size_t n = sock.receive(bufs);
+ *
+ * // received data is "committed" from output sequence to input sequence
+ * b.commit(n);
+ *
+ * std::istream is(&b);
+ * std::string s;
+ * is >> s;
+ * @endcode

+/// Provides waitable timer functionality.
+/**
+ * The basic_waitable_timer class template provides the ability to perform a
+ * blocking or asynchronous wait for a timer to expire.
+ *
+ * A waitable timer is always in one of two states: "expired" or "not expired".
+ * If the wait() or async_wait() function is called on an expired timer, the
+ * wait operation will complete immediately.
+ *
+ * Most applications will use one of the asio::steady_timer,
+ * asio::system_timer or asio::high_resolution_timer typedefs.
+ *
+ * @note This waitable timer functionality is for use with the C++11 standard
+ * library's @c &lt;chrono&gt; facility, or with the Boost.Chrono library.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Examples
+ * Performing a blocking wait (C++11):
+ * @code
+ * // Construct a timer without setting an expiry time.
+ * asio::steady_timer timer(my_context);
+ *
+ * // Set an expiry time relative to now.
+ * timer.expires_after(std::chrono::seconds(5));
+ *
+ * // Wait for the timer to expire.
+ * timer.wait();
+ * @endcode
+ *
+ * @par 
+ * Performing an asynchronous wait (C++11):
+ * @code
+ * void handler(const asio::error_code& error)
+ * {
+ *   if (!error)
+ *   {
+ *     // Timer expired.
+ *   }
+ * }
+ *
+ * ...
+ *
+ * // Construct a timer with an absolute expiry time.
+ * asio::steady_timer timer(my_context,
+ *     std::chrono::steady_clock::now() + std::chrono::seconds(60));
+ *
+ * // Start an asynchronous wait.
+ * timer.async_wait(handler);
+ * @endcode
+ *
+ * @par Changing an active waitable timer's expiry time
+ *
+ * Changing the expiry time of a timer while there are pending asynchronous
+ * waits causes those wait operations to be cancelled. To ensure that the action
+ * associated with the timer is performed only once, use something like this:
+ * used:
+ *
+ * @code
+ * void on_some_event()
+ * {
+ *   if (my_timer.expires_after(seconds(5)) > 0)
+ *   {
+ *     // We managed to cancel the timer. Start new asynchronous wait.
+ *     my_timer.async_wait(on_timeout);
+ *   }
+ *   else
+ *   {
+ *     // Too late, timer has already expired!
+ *   }
+ * }
+ *
+ * void on_timeout(const asio::error_code& e)
+ * {
+ *   if (e != asio::error::operation_aborted)
+ *   {
+ *     // Timer was not cancelled, take necessary action.
+ *   }
+ * }
+ * @endcode
+ *
+ * @li The asio::basic_waitable_timer::expires_after() function
+ * cancels any pending asynchronous waits, and returns the number of
+ * asynchronous waits that were cancelled. If it returns 0 then you were too
+ * late and the wait handler has already been executed, or will soon be
+ * executed. If it returns 1 then the wait handler was successfully cancelled.
+ *
+ * @li If a wait handler is cancelled, the asio::error_code passed to
+ * it contains the value asio::error::operation_aborted.

+/** @defgroup buffer asio::buffer
+ *
+ * @brief The asio::buffer function is used to create a buffer object to
+ * represent raw memory, an array of POD elements, a vector of POD elements,
+ * or a std::string.
+ *
+ * A buffer object represents a contiguous region of memory as a 2-tuple
+ * consisting of a pointer and size in bytes. A tuple of the form <tt>{void*,
+ * size_t}</tt> specifies a mutable (modifiable) region of memory. Similarly, a
+ * tuple of the form <tt>{const void*, size_t}</tt> specifies a const
+ * (non-modifiable) region of memory. These two forms correspond to the classes
+ * mutable_buffer and const_buffer, respectively. To mirror C++'s conversion
+ * rules, a mutable_buffer is implicitly convertible to a const_buffer, and the
+ * opposite conversion is not permitted.
+ *
+ * The simplest use case involves reading or writing a single buffer of a
+ * specified size:
+ *
+ * @code sock.send(asio::buffer(data, size)); @endcode
+ *
+ * In the above example, the return value of asio::buffer meets the
+ * requirements of the ConstBufferSequence concept so that it may be directly
+ * passed to the socket's write function. A buffer created for modifiable
+ * memory also meets the requirements of the MutableBufferSequence concept.
+ *
+ * An individual buffer may be created from a builtin array, std::vector,
+ * std::array or boost::array of POD elements. This helps prevent buffer
+ * overruns by automatically determining the size of the buffer:
+ *
+ * @code char d1[128];
+ * size_t bytes_transferred = sock.receive(asio::buffer(d1));
+ *
+ * std::vector<char> d2(128);
+ * bytes_transferred = sock.receive(asio::buffer(d2));
+ *
+ * std::array<char, 128> d3;
+ * bytes_transferred = sock.receive(asio::buffer(d3));
+ *
+ * boost::array<char, 128> d4;
+ * bytes_transferred = sock.receive(asio::buffer(d4)); @endcode
+ *
+ * In all three cases above, the buffers created are exactly 128 bytes long.
+ * Note that a vector is @e never automatically resized when creating or using
+ * a buffer. The buffer size is determined using the vector's <tt>size()</tt>
+ * member function, and not its capacity.
+ *
+ * @par Accessing Buffer Contents
+ *
+ * The contents of a buffer may be accessed using the @c data() and @c size()
+ * member functions:
+ *
+ * @code asio::mutable_buffer b1 = ...;
+ * std::size_t s1 = b1.size();
+ * unsigned char* p1 = static_cast<unsigned char*>(b1.data());
+ *
+ * asio::const_buffer b2 = ...;
+ * std::size_t s2 = b2.size();
+ * const void* p2 = b2.data(); @endcode
+ *
+ * The @c data() member function permits violations of type safety, so
+ * uses of it in application code should be carefully considered.
+ *
+ * For convenience, a @ref buffer_size function is provided that works with
+ * both buffers and buffer sequences (that is, types meeting the
+ * ConstBufferSequence or MutableBufferSequence type requirements). In this
+ * case, the function returns the total size of all buffers in the sequence.
+ *
+ * @par Buffer Copying
+ *
+ * The @ref buffer_copy function may be used to copy raw bytes between
+ * individual buffers and buffer sequences.
+*
+ * In particular, when used with the @ref buffer_size function, the @ref
+ * buffer_copy function can be used to linearise a sequence of buffers. For
+ * example:
+ *
+ * @code vector<const_buffer> buffers = ...;
+ *
+ * vector<unsigned char> data(asio::buffer_size(buffers));
+ * asio::buffer_copy(asio::buffer(data), buffers); @endcode
+ *
+ * Note that @ref buffer_copy is implemented in terms of @c memcpy, and
+ * consequently it cannot be used to copy between overlapping memory regions.
+ *
+ * @par Buffer Invalidation
+ *
+ * A buffer object does not have any ownership of the memory it refers to. It
+ * is the responsibility of the application to ensure the memory region remains
+ * valid until it is no longer required for an I/O operation. When the memory
+ * is no longer available, the buffer is said to have been invalidated.
+ *
+ * For the asio::buffer overloads that accept an argument of type
+ * std::vector, the buffer objects returned are invalidated by any vector
+ * operation that also invalidates all references, pointers and iterators
+ * referring to the elements in the sequence (C++ Std, 23.2.4)
+ *
+ * For the asio::buffer overloads that accept an argument of type
+ * std::basic_string, the buffer objects returned are invalidated according to
+ * the rules defined for invalidation of references, pointers and iterators
+ * referring to elements of the sequence (C++ Std, 21.3).
+ *
+ * @par Buffer Arithmetic
+ *
+ * Buffer objects may be manipulated using simple arithmetic in a safe way
+ * which helps prevent buffer overruns. Consider an array initialised as
+ * follows:
+ *
+ * @code boost::array<char, 6> a = { 'a', 'b', 'c', 'd', 'e' }; @endcode
+ *
+ * A buffer object @c b1 created using:
+ *
+ * @code b1 = asio::buffer(a); @endcode
+ *
+ * represents the entire array, <tt>{ 'a', 'b', 'c', 'd', 'e' }</tt>. An
+ * optional second argument to the asio::buffer function may be used to
+ * limit the size, in bytes, of the buffer:
+ *
+ * @code b2 = asio::buffer(a, 3); @endcode
+ *
+ * such that @c b2 represents the data <tt>{ 'a', 'b', 'c' }</tt>. Even if the
+ * size argument exceeds the actual size of the array, the size of the buffer
+ * object created will be limited to the array size.
+ *
+ * An offset may be applied to an existing buffer to create a new one:
+ *
+ * @code b3 = b1 + 2; @endcode
+ *
+ * where @c b3 will set to represent <tt>{ 'c', 'd', 'e' }</tt>. If the offset
+ * exceeds the size of the existing buffer, the newly created buffer will be
+ * empty.
+ *
+ * Both an offset and size may be specified to create a buffer that corresponds
+ * to a specific range of bytes within an existing buffer:
+ *
+ * @code b4 = asio::buffer(b1 + 1, 3); @endcode
+ *
+ * so that @c b4 will refer to the bytes <tt>{ 'b', 'c', 'd' }</tt>.
+ *
+ * @par Buffers and Scatter-Gather I/O
+ *
+ * To read or write using multiple buffers (i.e. scatter-gather I/O), multiple
+ * buffer objects may be assigned into a container that supports the
+ * MutableBufferSequence (for read) or ConstBufferSequence (for write) concepts:
+ *
+ * @code
+ * char d1[128];
+ * std::vector<char> d2(128);
+ * boost::array<char, 128> d3;
+ *
+ * boost::array<mutable_buffer, 3> bufs1 = {
+ *   asio::buffer(d1),
+ *   asio::buffer(d2),
+ *   asio::buffer(d3) };
+ * bytes_transferred = sock.receive(bufs1);
+ *
+ * std::vector<const_buffer> bufs2;
+ * bufs2.push_back(asio::buffer(d1));
+ * bufs2.push_back(asio::buffer(d2));
+ * bufs2.push_back(asio::buffer(d3));
+ * bytes_transferred = sock.send(bufs2); @endcode

+ *
+ * @li A 3-argument form: @c buffer_copy(target, source, max_bytes_to_copy)
+ *

+ *
+ * @li @c buffer_size(target)
+ *
+ * @li @c buffer_size(source)
+ *
+ * @li @c If specified, @c max_bytes_to_copy.
+ *
+ * This prevents buffer overflow, regardless of the buffer sizes used in the

+
+/// Provides support for implementing stackless coroutines.
+/**
+ * The @c coroutine class may be used to implement stackless coroutines. The
+ * class itself is used to store the current state of the coroutine.
+ *
+ * Coroutines are copy-constructible and assignable, and the space overhead is
+ * a single int. They can be used as a base class:
+ *
+ * @code class session : coroutine
+ * {
+ *   ...
+ * }; @endcode
+ *
+ * or as a data member:
+ *
+ * @code class session
+ * {
+ *   ...
+ *   coroutine coro_;
+ * }; @endcode
+ *
+ * or even bound in as a function argument using lambdas or @c bind(). The
+ * important thing is that as the application maintains a copy of the object
+ * for as long as the coroutine must be kept alive.
+ *
+ * @par Pseudo-keywords
+ *
+ * A coroutine is used in conjunction with certain "pseudo-keywords", which
+ * are implemented as macros. These macros are defined by a header file:
+ *
+ * @code #include <asio/yield.hpp>@endcode
+ *
+ * and may conversely be undefined as follows:
+ *
+ * @code #include <asio/unyield.hpp>@endcode
+ *
+ * <b>reenter</b>
+ *
+ * The @c reenter macro is used to define the body of a coroutine. It takes a
+ * single argument: a pointer or reference to a coroutine object. For example,
+ * if the base class is a coroutine object you may write:
+ *
+ * @code reenter (this)
+ * {
+ *   ... coroutine body ...
+ * } @endcode
+ *
+ * and if a data member or other variable you can write:
+ *
+ * @code reenter (coro_)
+ * {
+ *   ... coroutine body ...
+ * } @endcode
+ *
+ * When @c reenter is executed at runtime, control jumps to the location of the
+ * last @c yield or @c fork.
+ *
+ * The coroutine body may also be a single statement, such as:
+ *
+ * @code reenter (this) for (;;)
+ * {
+ *   ...
+ * } @endcode
+ *
+ * @b Limitation: The @c reenter macro is implemented using a switch. This
+ * means that you must take care when using local variables within the
+ * coroutine body. The local variable is not allowed in a position where
+ * reentering the coroutine could bypass the variable definition.
+ *
+ * <b>yield <em>statement</em></b>
+ *
+ * This form of the @c yield keyword is often used with asynchronous operations:
+ *
+ * @code yield socket_->async_read_some(buffer(*buffer_), *this); @endcode
+ *
+ * This divides into four logical steps:
+ *
+ * @li @c yield saves the current state of the coroutine.
+ * @li The statement initiates the asynchronous operation.
+ * @li The resume point is defined immediately following the statement.
+ * @li Control is transferred to the end of the coroutine body.
+ *
+ * When the asynchronous operation completes, the function object is invoked
+ * and @c reenter causes control to transfer to the resume point. It is
+ * important to remember to carry the coroutine state forward with the
+ * asynchronous operation. In the above snippet, the current class is a
+ * function object object with a coroutine object as base class or data member.
+ *
+ * The statement may also be a compound statement, and this permits us to
+ * define local variables with limited scope:
+ *
+ * @code yield
+ * {
+ *   mutable_buffers_1 b = buffer(*buffer_);
+ *   socket_->async_read_some(b, *this);
+ * } @endcode
+ *
+ * <b>yield return <em>expression</em> ;</b>
+ *
+ * This form of @c yield is often used in generators or coroutine-based parsers.
+ * For example, the function object:
+ *
+ * @code struct interleave : coroutine
+ * {
+ *   istream& is1;
+ *   istream& is2;
+ *   char operator()(char c)
+ *   {
+ *     reenter (this) for (;;)
+ *     {
+ *       yield return is1.get();
+ *       yield return is2.get();
+ *     }
+ *   }
+ * }; @endcode
+ *
+ * defines a trivial coroutine that interleaves the characters from two input
+ * streams.
+ *
+ * This type of @c yield divides into three logical steps:
+ *
+ * @li @c yield saves the current state of the coroutine.
+ * @li The resume point is defined immediately following the semicolon.
+ * @li The value of the expression is returned from the function.
+ *
+ * <b>yield ;</b>
+ *
+ * This form of @c yield is equivalent to the following steps:
+ *
+ * @li @c yield saves the current state of the coroutine.
+ * @li The resume point is defined immediately following the semicolon.
+ * @li Control is transferred to the end of the coroutine body.
+ *
+ * This form might be applied when coroutines are used for cooperative
+ * threading and scheduling is explicitly managed. For example:
+ *
+ * @code struct task : coroutine
+ * {
+ *   ...
+ *   void operator()()
+ *   {
+ *     reenter (this)
+ *     {
+ *       while (... not finished ...)
+ *       {
+ *         ... do something ...
+ *         yield;
+ *         ... do some more ...
+ *         yield;
+ *       }
+ *     }
+ *   }
+ *   ...
+ * };
+ * ...
+ * task t1, t2;
+ * for (;;)
+ * {
+ *   t1();
+ *   t2();
+ * } @endcode
+ *
+ * <b>yield break ;</b>
+ *
+ * The final form of @c yield is used to explicitly terminate the coroutine.
+ * This form is comprised of two steps:
+ *
+ * @li @c yield sets the coroutine state to indicate termination.
+ * @li Control is transferred to the end of the coroutine body.
+ *
+ * Once terminated, calls to is_complete() return true and the coroutine cannot
+ * be reentered.
+ *
+ * Note that a coroutine may also be implicitly terminated if the coroutine
+ * body is exited without a yield, e.g. by return, throw or by running to the
+ * end of the body.
+ *
+ * <b>fork <em>statement</em></b>
+ *
+ * The @c fork pseudo-keyword is used when "forking" a coroutine, i.e. splitting
+ * it into two (or more) copies. One use of @c fork is in a server, where a new
+ * coroutine is created to handle each client connection:
+ * 
+ * @code reenter (this)
+ * {
+ *   do
+ *   {
+ *     socket_.reset(new tcp::socket(my_context_));
+ *     yield acceptor->async_accept(*socket_, *this);
+ *     fork server(*this)();
+ *   } while (is_parent());
+ *   ... client-specific handling follows ...
+ * } @endcode
+ * 
+ * The logical steps involved in a @c fork are:
+ * 
+ * @li @c fork saves the current state of the coroutine.
+ * @li The statement creates a copy of the coroutine and either executes it
+ *     immediately or schedules it for later execution.
+ * @li The resume point is defined immediately following the semicolon.
+ * @li For the "parent", control immediately continues from the next line.
+ *
+ * The functions is_parent() and is_child() can be used to differentiate
+ * between parent and child. You would use these functions to alter subsequent
+ * control flow.
+ *
+ * Note that @c fork doesn't do the actual forking by itself. It is the
+ * application's responsibility to create a clone of the coroutine and call it.
+ * The clone can be called immediately, as above, or scheduled for delayed
+ * execution using something like asio::post().
+ *
+ * @par Alternate macro names
+ *
+ * If preferred, an application can use macro names that follow a more typical
+ * naming convention, rather than the pseudo-keywords. These are:
+ *
+ * @li @c ASIO_CORO_REENTER instead of @c reenter
+ * @li @c ASIO_CORO_YIELD instead of @c yield
+ * @li @c ASIO_CORO_FORK instead of @c fork

+ *   object <tt>F</tt> on the executor <tt>S</tt> in bulk with forward progress
+ *   guarantee <tt>asio::query(S, execution::bulk_guarantee)</tt>, and
+ *   the result of that function does not model <tt>sender<void></tt>, the

+/// A context for function object execution.
+/**
+ * An execution context represents a place where function objects will be
+ * executed. An @c io_context is an example of an execution context.
+ *
+ * @par The execution_context class and services
+ *
+ * Class execution_context implements an extensible, type-safe, polymorphic set
+ * of services, indexed by service type.
+ *
+ * Services exist to manage the resources that are shared across an execution
+ * context. For example, timers may be implemented in terms of a single timer
+ * queue, and this queue would be stored in a service.
+ *
+ * Access to the services of an execution_context is via three function
+ * templates, use_service(), add_service() and has_service().
+ *
+ * In a call to @c use_service<Service>(), the type argument chooses a service,
+ * making available all members of the named type. If @c Service is not present
+ * in an execution_context, an object of type @c Service is created and added
+ * to the execution_context. A C++ program can check if an execution_context
+ * implements a particular service with the function template @c
+ * has_service<Service>().
+ *
+ * Service objects may be explicitly added to an execution_context using the
+ * function template @c add_service<Service>(). If the @c Service is already
+ * present, the service_already_exists exception is thrown. If the owner of the
+ * service is not the same object as the execution_context parameter, the
+ * invalid_service_owner exception is thrown.
+ *
+ * Once a service reference is obtained from an execution_context object by
+ * calling use_service(), that reference remains usable as long as the owning
+ * execution_context object exists.
+ *
+ * All service implementations have execution_context::service as a public base
+ * class. Custom services may be implemented by deriving from this class and
+ * then added to an execution_context using the facilities described above.
+ *
+ * @par The execution_context as a base class
+ *
+ * Class execution_context may be used only as a base class for concrete
+ * execution context types. The @c io_context is an example of such a derived
+ * type.
+ *
+ * On destruction, a class that is derived from execution_context must perform
+ * <tt>execution_context::shutdown()</tt> followed by
+ * <tt>execution_context::destroy()</tt>.
+ *
+ * This destruction sequence permits programs to simplify their resource
+ * management by using @c shared_ptr<>. Where an object's lifetime is tied to
+ * the lifetime of a connection (or some other sequence of asynchronous
+ * operations), a @c shared_ptr to the object would be bound into the handlers
+ * for all asynchronous operations associated with it. This works as follows:
+ *
+ * @li When a single connection ends, all associated asynchronous operations
+ * complete. The corresponding handler objects are destroyed, and all @c
+ * shared_ptr references to the objects are destroyed.
+ *
+ * @li To shut down the whole program, the io_context function stop() is called
+ * to terminate any run() calls as soon as possible. The io_context destructor
+ * calls @c shutdown() and @c destroy() to destroy all pending handlers,
+ * causing all @c shared_ptr references to all connection objects to be
+ * destroyed.

+ * @brief (Deprecated: Use the associated_executor trait.) Default invoke
+ * function for handlers.
+ *
+ * Completion handlers for asynchronous operations are invoked by the
+ * io_context associated with the corresponding object (e.g. a socket or
+ * deadline_timer). Certain guarantees are made on when the handler may be
+ * invoked, in particular that a handler can only be invoked from a thread that
+ * is currently calling @c run() on the corresponding io_context object.
+ * Handlers may subsequently be invoked through other objects (such as
+ * io_context::strand objects) that provide additional guarantees.
+ *
+ * When asynchronous operations are composed from other asynchronous
+ * operations, all intermediate handlers should be invoked using the same
+ * method as the final handler. This is required to ensure that user-defined
+ * objects are not accessed in a way that may violate the guarantees. This
+ * hooking function ensures that the invoked method used for the final handler
+ * is accessible at each intermediate step.
+ *
+ * Implement asio_handler_invoke for your own handlers to specify a custom
+ * invocation strategy.
+ *
+ * This default implementation invokes the function object like so:
+ * @code function(); @endcode
+ * If necessary, the default implementation makes a copy of the function object
+ * so that the non-const operator() can be used.
+ *
+ * @par Example
+ * @code
+ * class my_handler;

+/// Provides core I/O functionality.
+/**
+ * The io_context class provides the core I/O functionality for users of the
+ * asynchronous I/O objects, including:
+ *
+ * @li asio::ip::tcp::socket
+ * @li asio::ip::tcp::acceptor
+ * @li asio::ip::udp::socket
+ * @li asio::deadline_timer.
+ *
+ * The io_context class also includes facilities intended for developers of
+ * custom asynchronous services.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Safe, with the specific exceptions of the restart()
+ * and notify_fork() functions. Calling restart() while there are unfinished
+ * run(), run_one(), run_for(), run_until(), poll() or poll_one() calls results
+ * in undefined behaviour. The notify_fork() function should not be called
+ * while any io_context function, or any function on an I/O object that is
+ * associated with the io_context, is being called in another thread.
+ *
+ * @par Concepts:
+ * Dispatcher.
+ *
+ * @par Synchronous and asynchronous operations
+ *
+ * Synchronous operations on I/O objects implicitly run the io_context object
+ * for an individual operation. The io_context functions run(), run_one(),
+ * run_for(), run_until(), poll() or poll_one() must be called for the
+ * io_context to perform asynchronous operations on behalf of a C++ program.
+ * Notification that an asynchronous operation has completed is delivered by
+ * invocation of the associated handler. Handlers are invoked only by a thread
+ * that is currently calling any overload of run(), run_one(), run_for(),
+ * run_until(), poll() or poll_one() for the io_context.
+ *
+ * @par Effect of exceptions thrown from handlers
+ *
+ * If an exception is thrown from a handler, the exception is allowed to
+ * propagate through the throwing thread's invocation of run(), run_one(),
+ * run_for(), run_until(), poll() or poll_one(). No other threads that are
+ * calling any of these functions are affected. It is then the responsibility
+ * of the application to catch the exception.
+ *
+ * After the exception has been caught, the run(), run_one(), run_for(),
+ * run_until(), poll() or poll_one() call may be restarted @em without the need
+ * for an intervening call to restart(). This allows the thread to rejoin the
+ * io_context object's thread pool without impacting any other threads in the
+ * pool.
+ *
+ * For example:
+ *
+ * @code
+ * asio::io_context io_context;
+ * ...
+ * for (;;)
+ * {
+ *   try
+ *   {
+ *     io_context.run();
+ *     break; // run() exited normally
+ *   }
+ *   catch (my_exception& e)
+ *   {
+ *     // Deal with exception as appropriate.
+ *   }
+ * }
+ * @endcode
+ *
+ * @par Submitting arbitrary tasks to the io_context
+ *
+ * To submit functions to the io_context, use the @ref asio::dispatch,
+ * @ref asio::post or @ref asio::defer free functions.
+ *
+ * For example:
+ *
+ * @code void my_task()
+ * {
+ *   ...
+ * }
+ *
+ * ...
+ *
+ * asio::io_context io_context;
+ *
+ * // Submit a function to the io_context.
+ * asio::post(io_context, my_task);
+ *
+ * // Submit a lambda object to the io_context.
+ * asio::post(io_context,
+ *     []()
+ *     {
+ *       ...
+ *     });
+ *
+ * // Run the io_context until it runs out of work.
+ * io_context.run(); @endcode
+ *
+ * @par Stopping the io_context from running out of work
+ *
+ * Some applications may need to prevent an io_context object's run() call from
+ * returning when there is no more work to do. For example, the io_context may
+ * be being run in a background thread that is launched prior to the
+ * application's asynchronous operations. The run() call may be kept running by
+ * creating an executor that tracks work against the io_context:
+ *
+ * @code asio::io_context io_context;
+ * auto work = asio::require(io_context.get_executor(),
+ *     asio::execution::outstanding_work.tracked);
+ * ... @endcode
+ *
+ * If using C++03, which lacks automatic variable type deduction, you may
+ * compute the return type of the require call:
+ *
+ * @code asio::io_context io_context;
+ * typename asio::require_result<
+ *     asio::io_context::executor_type,
+ *     asio::exeution::outstanding_work_t::tracked_t>
+ *   work = asio::require(io_context.get_executor(),
+ *     asio::execution::outstanding_work.tracked);
+ * ... @endcode
+ *
+ * or store the result in the type-erasing executor wrapper, any_io_executor:
+ *
+ * @code asio::io_context io_context;
+ * asio::any_io_executor work
+ *   = asio::require(io_context.get_executor(),
+ *       asio::execution::outstanding_work.tracked);
+ * ... @endcode
+ *
+ * To effect a shutdown, the application will then need to call the io_context
+ * object's stop() member function. This will cause the io_context run() call
+ * to return as soon as possible, abandoning unfinished operations and without
+ * permitting ready handlers to be dispatched.
+ *
+ * Alternatively, if the application requires that all operations and handlers
+ * be allowed to finish normally, store the work-tracking executor in an
+ * any_io_executor object, so that it may be explicitly reset.
+ *
+ * @code asio::io_context io_context;
+ * asio::any_io_executor work
+ *   = asio::require(io_context.get_executor(),
+ *       asio::execution::outstanding_work.tracked);
+ * ...
+ * work = asio::any_io_executor(); // Allow run() to exit. @endcode

+ * The io_context::strand class provides the ability to post and dispatch
+ * handlers with the guarantee that none of those handlers will execute
+ * concurrently.
+ *
+ * @par Order of handler invocation
+ * Given:
+ *
+ * @li a strand object @c s
+ *
+ * @li an object @c a meeting completion handler requirements
+ *
+ * @li an object @c a1 which is an arbitrary copy of @c a made by the
+ * implementation
+ *
+ * @li an object @c b meeting completion handler requirements
+ *
+ * @li an object @c b1 which is an arbitrary copy of @c b made by the
+ * implementation
+ *
+ * if any of the following conditions are true:
+ *
+ * @li @c s.post(a) happens-before @c s.post(b)
+ * 
+ * @li @c s.post(a) happens-before @c s.dispatch(b), where the latter is
+ * performed outside the strand
+ * 
+ * @li @c s.dispatch(a) happens-before @c s.post(b), where the former is
+ * performed outside the strand
+ * 
+ * @li @c s.dispatch(a) happens-before @c s.dispatch(b), where both are
+ * performed outside the strand
+ *   
+ * then @c asio_handler_invoke(a1, &a1) happens-before
+ * @c asio_handler_invoke(b1, &b1).
+ * 
+ * Note that in the following case:
+ * @code async_op_1(..., s.wrap(a));
+ * async_op_2(..., s.wrap(b)); @endcode
+ * the completion of the first async operation will perform @c s.dispatch(a),
+ * and the second will perform @c s.dispatch(b), but the order in which those
+ * are performed is unspecified. That is, you cannot state whether one
+ * happens-before the other. Therefore none of the above conditions are met and
+ * no ordering guarantee is made.
+ *
+ * @note The implementation makes no guarantee that handlers posted or
+ * dispatched through different @c strand objects will be invoked concurrently.
+ *
+ * @par Thread Safety

+/**
+ * This function is used to read data into the specified dynamic buffer
+ * sequence until the dynamic buffer sequence's get area contains some data
+ * that matches a regular expression. The call will block until one of the
+ * following conditions is true:
+ *
+ * @li A substring of the dynamic buffer sequence's get area matches the
+ * regular expression.
+ *
+ * @li An error occurred.
+ *
+ * This operation is implemented in terms of zero or more calls to the stream's
+ * read_some function. If the dynamic buffer sequence's get area already
+ * contains data that matches the regular expression, the function returns
+ * immediately.
+ *
+ * @param s The stream from which the data is to be read. The type must support
+ * the SyncReadStream concept.
+ *
+ * @param buffers A dynamic buffer sequence into which the data will be read.
+ *
+ * @param expr The regular expression.
+ *
+ * @returns The number of bytes in the dynamic buffer sequence's get area up to
+ * and including the substring that matches the regular expression.
+ *
+ * @throws asio::system_error Thrown on failure.
+ *
+ * @note After a successful read_until operation, the dynamic buffer sequence
+ * may contain additional data beyond that which matched the regular
+ * expression. An application will typically leave that data in the dynamic
+ * buffer sequence for a subsequent read_until operation to examine.
+ *
+ * @par Example
+ * To read data into a @c std::string until a CR-LF sequence is encountered:
+ * @code std::string data;
+ * std::size_t n = asio::read_until(s,
+ *     asio::dynamic_buffer(data), boost::regex("\r\n"));
+ * std::string line = data.substr(0, n);
+ * data.erase(0, n); @endcode
+ * After the @c read_until operation completes successfully, the string @c data
+ * contains the delimiter:
+ * @code { 'a', 'b', ..., 'c', '\r', '\n', 'd', 'e', ... } @endcode
+ * The call to @c substr then extracts the data up to and including the
+ * delimiter, so that the string @c line contains:
+ * @code { 'a', 'b', ..., 'c', '\r', '\n' } @endcode
+ * After the call to @c erase, the remaining data is left in the buffer @c b as
+ * follows:
+ * @code { 'd', 'e', ... } @endcode
+ * This data may be the start of a new line, to be extracted by a subsequent

+ * the match condition function object already indicates a match, this
+ * asynchronous operation completes immediately. The program must ensure that
+ * the stream performs no other read operations (such as async_read,
+ * async_read_until, the stream's async_read_some function, or any other
+ * composed operations that perform reads) until this operation completes.
+ *
+ * @param s The stream from which the data is to be read. The type must support
+ * the AsyncReadStream concept.
+ *
+ * @param buffers The dynamic buffer sequence into which the data will be read.
+ * Although the buffers object may be copied as necessary, ownership of the
+ * underlying memory blocks is retained by the caller, which must guarantee
+ * that they remain valid until the handler is called.
+ *
+ * @param match_condition The function object to be called to determine whether
+ * a match exists. The signature of the function object must be:
+ * @code pair<iterator, bool> match_condition(iterator begin, iterator end);
+ * @endcode
+ * where @c iterator represents the type:
+ * @code buffers_iterator<typename DynamicBuffer_v2::const_buffers_type>
+ * @endcode
+ * The iterator parameters @c begin and @c end define the range of bytes to be
+ * scanned to determine whether there is a match. The @c first member of the
+ * return value is an iterator marking one-past-the-end of the bytes that have
+ * been consumed by the match function. This iterator is used to calculate the
+ * @c begin parameter for any subsequent invocation of the match condition. The
+ * @c second member of the return value is true if a match has been found, false
+ * otherwise.
+ *
+ * @param handler The handler to be called when the read operation completes.
+ * Copies will be made of the handler as required. The function signature of the
+ * handler must be:
+ * @code void handler(
+ *   // Result of operation.
+ *   const asio::error_code& error,
+ *
+ *   // The number of bytes in the dynamic buffer sequence's
+ *   // get area that have been fully consumed by the match
+ *   // function. O if an error occurred.
+ *   std::size_t bytes_transferred
+ * ); @endcode
+ * Regardless of whether the asynchronous operation completes immediately or
+ * not, the handler will not be invoked from within this function. On
+ * immediate completion, invocation of the handler will be performed in a
+ * manner equivalent to using asio::post().
+ *
+ * @note After a successful async_read_until operation, the dynamic buffer
+ * sequence may contain additional data beyond that which matched the function
+ * object. An application will typically leave that data in the dynamic buffer
+ * sequence for a subsequent async_read_until operation to examine.
+ *
+ * @note The default implementation of the @c is_match_condition type trait
+ * evaluates to true for function pointers and function objects with a
+ * @c result_type typedef. It must be specialised for other user-defined
+ * function objects.
+ *
+ * @par Examples
+ * To asynchronously read data into a @c std::string until whitespace is
+ * encountered:
+ * @code typedef asio::buffers_iterator<
+ *     asio::const_buffers_1> iterator;
+ *
+ * std::pair<iterator, bool>
+ * match_whitespace(iterator begin, iterator end)
+ * {
+ *   iterator i = begin;
+ *   while (i != end)
+ *     if (std::isspace(*i++))
+ *       return std::make_pair(i, true);
+ *   return std::make_pair(i, false);
+ * }
+ * ...
+ * void handler(const asio::error_code& e, std::size_t size);
+ * ...
+ * std::string data;
+ * asio::async_read_until(s, data, match_whitespace, handler);
+ * @endcode
+ *
+ * To asynchronously read data into a @c std::string until a matching character
+ * is found:
+ * @code class match_char
+ * {
+ * public:
+ *   explicit match_char(char c) : c_(c) {}
+ *
+ *   template <typename Iterator>
+ *   std::pair<Iterator, bool> operator()(
+ *       Iterator begin, Iterator end) const
+ *   {
+ *     Iterator i = begin;
+ *     while (i != end)
+ *       if (c_ == *i++)
+ *         return std::make_pair(i, true);
+ *     return std::make_pair(i, false);
+ *   }

+ *   char c_;

+ * This function is used to asynchronously write a certain number of bytes of

+ * @li All of the data in the supplied buffers has been written. That is, the

+ * @li An error occurred.
+ *
+ * This operation is implemented in terms of zero or more calls to the stream's

+/// Start an asynchronous operation to write a certain amount of data at the

+/**
+ * This function is used to asynchronously write a certain number of bytes of
+ * data to a random access device at a specified offset. The function call
+ * always returns immediately. The asynchronous operation will continue until
+ * one of the following conditions is true:
+ *
+ * @li All of the data in the supplied basic_streambuf has been written.
+ *
+ * @li The completion_condition function object returns 0.
+ *
+ * This operation is implemented in terms of zero or more calls to the device's
+ * async_write_some_at function, and is known as a <em>composed operation</em>.
+ * The program must ensure that the device performs no <em>overlapping</em>
+ * write operations (such as async_write_at, the device's async_write_some_at
+ * function, or any other composed operations that perform writes) until this
+ * operation completes. Operations are overlapping if the regions defined by
+ * their offsets, and the numbers of bytes to write, intersect.
+ *
+ * @param d The device to which the data is to be written. The type must support
+ * the AsyncRandomAccessWriteDevice concept.
+ *
+ * @param offset The offset at which the data will be written.
+ *
+ * @param b A basic_streambuf object from which data will be written. Ownership
+ * of the streambuf is retained by the caller, which must guarantee that it
+ * remains valid until the handler is called.
+ *
+ * @param completion_condition The function object to be called to determine
+ * whether the write operation is complete. The signature of the function object
+ * must be:
+ * @code std::size_t completion_condition(
+ *   // Result of latest async_write_some_at operation.
+ *   const asio::error_code& error,
+ *
+ *   // Number of bytes transferred so far.
+ *   std::size_t bytes_transferred
+ * ); @endcode
+ * A return value of 0 indicates that the write operation is complete. A
+ * non-zero return value indicates the maximum number of bytes to be written on
+ * the next call to the device's async_write_some_at function.
+ *
+ * @param handler The handler to be called when the write operation completes.
+ * Copies will be made of the handler as required. The function signature of the
+ * handler must be:
+ * @code void handler(
+ *   // Result of operation.
+ *   const asio::error_code& error,
+ *
+ *   // Number of bytes written from the buffers. If an error
+ *   // occurred, this will be less than the sum of the buffer sizes.

+# Contributing to C++ Requests
+
+Please fork this repository and contribute back using [pull requests](https://github.com/whoshuu/cpr/pulls). Features can be requested using [issues](https://github.com/whoshuu/cpr/issues). All code, comments, and critiques are greatly appreciated.
+
+## Formatting
+
+To avoid unproductive debates on formatting, this project uses `clang-format` to ensure a consistent style across all source files. Currently, `clang-format` 3.8 is the version of `clang-format` we use. The format file can be found [here](https://github.com/whoshuu/cpr/blob/master/.clang-format). To install `clang-format` on Ubuntu, run this:
+
+```
+apt-get install clang-format-3.8
+```
+
+To install `clang-format` on OS X, run this:
+
+```
+brew install clang-format
+```
+
+Note that `brew` might install a later version of `clang-format`, but it should be mostly compatible with what's run on the Travis servers.
+
+To run `clang-format` on every source file, run this in the root directory:
+
+```
+./format-check.sh
+```
+
+This should indicate which files need formatting and also show a diff of the requested changes. More specific usage instructions can be found on the official [LLVM website](http://releases.llvm.org/3.8.0/tools/clang/docs/ClangFormat.html).

+# C++ Requests: Curl for People <img align="right" height="40" src="http://i.imgur.com/d9Xtyts.png">
+
+[![Documentation](https://img.shields.io/badge/docs-online-informational?style=flat&link=https://whoshuu.github.io/cpr/)](https://whoshuu.github.io/cpr/)
+![CI](https://github.com/whoshuu/cpr/workflows/CI/badge.svg)
+
+## Announcements
+
+The cpr project has new maintainers: [Fabian Sauter](https://github.com/com8) and [Tim Stack](https://github.com/tstack).
+
+## TLDR
+
+C++ Requests is a simple wrapper around [libcurl](http://curl.haxx.se/libcurl) inspired by the excellent [Python Requests](https://github.com/kennethreitz/requests) project.
+
+Despite its name, libcurl's easy interface is anything but, and making mistakes misusing it is a common source of error and frustration. Using the more expressive language facilities of C++11, this library captures the essence of making network calls into a few concise idioms.
+
+Here's a quick GET request:
+
+```c++
+#include <cpr/cpr.h>
+
+int main(int argc, char** argv) {
+    cpr::Response r = cpr::Get(cpr::Url{"https://api.github.com/repos/whoshuu/cpr/contributors"},
+                      cpr::Authentication{"user", "pass"},
+                      cpr::Parameters{{"anon", "true"}, {"key", "value"}});
+    r.status_code;                  // 200
+    r.header["content-type"];       // application/json; charset=utf-8
+    r.text;                         // JSON text string
+}
+```
+
+And here's [less functional, more complicated code, without cpr](https://gist.github.com/whoshuu/2dc858b8730079602044).
+
+## Documentation
+
+[![Documentation](https://img.shields.io/badge/docs-online-informational?style=for-the-badge&link=https://whoshuu.github.io/cpr/)](https://whoshuu.github.io/cpr/)  
+You can find the latest documentation [here](https://whoshuu.github.io/cpr). It's a work in progress, but it should give you a better idea of how to use the library than the [tests](https://github.com/whoshuu/cpr/tree/master/test) currently do.
+
+## Features
+
+C++ Requests currently supports:
+
+* Custom headers
+* Url encoded parameters
+* Url encoded POST values
+* Multipart form POST upload
+* File POST upload
+* Basic authentication
+* Bearer authentication
+* Digest authentication
+* NTLM authentication
+* Connection and request timeout specification
+* Timeout for low speed connection
+* Asynchronous requests
+* :cookie: support!
+* Proxy support
+* Callback interfaces
+* PUT methods
+* DELETE methods
+* HEAD methods
+* OPTIONS methods
+* PATCH methods
+* Thread Safe access to [libCurl](https://curl.haxx.se/libcurl/c/threadsafe.html)
+* OpenSSL and WinSSL support for HTTPS requests
+
+## Planned
+
+For a quick overview about the planed features, have a look at the next [Milestones](https://github.com/whoshuu/cpr/milestones).
+
+## Usage
+
+If you already have a project you need to integrate C++ Requests with, the primary way is to use CMake `fetch_content`.
+Add the following to your `CMakeLists.txt`.
+
+
+```cmake
+include(FetchContent)
+FetchContent_Declare(cpr GIT_REPOSITORY https://github.com/whoshuu/cpr.git GIT_TAG c8d33915dbd88ad6c92b258869b03aba06587ff9) # the commit hash for 1.5.0
+FetchContent_MakeAvailable(cpr)
+```
+
+This will produce the target `cpr::cpr` which you can link against the typical way:
+
+```cmake
+target_link_libraries(your_target_name PRIVATE cpr::cpr)
+```
+
+That should do it!
+There's no need to handle `libcurl` yourself. All dependencies are taken care of for you.
+
+## Requirements
+
+The only explicit requirements are:
+
+* a `C++11` compatible compiler such as Clang or GCC. The minimum required version of GCC is unknown, so if anyone has trouble building this library with a specific version of GCC, do let me know
+* If you would like to perform https requests `OpenSSL` and its development libraries are required.
+
+## Building cpr - Using vcpkg
+
+You can download and install cpr using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
+```Bash
+git clone https://github.com/Microsoft/vcpkg.git
+cd vcpkg
+./bootstrap-vcpkg.sh
+./vcpkg integrate install
+./vcpkg install cpr
+```
+The `cpr` port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
+
+## Building cpr - Using Conan
+
+You can download and install `cpr` using the [Conan](https://conan.io/) package manager. Setup your CMakeLists.txt (see [Conan documentation](https://docs.conan.io/en/latest/integrations/build_system.html) on how to use MSBuild, Meson and others) like this:
+
+```CMake
+project(myproject CXX)
+
+add_executable(${PROJECT_NAME} main.cpp)
+
+include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake) # Include Conan-generated file
+conan_basic_setup(TARGETS) # Introduce Conan-generated targets
+
+target_link_libraries(${PROJECT_NAME} CONAN_PKG::cpr)
+```
+Create `conanfile.txt` in your source dir:
+```
+[requires]
+cpr/1.5.0
+
+[generators]
+cmake
+```
+Install and run Conan, then build your project as always:
+
+```Bash
+pip install conan
+mkdir build
+cd build
+conan install ../ --build=missing
+cmake ../
+cmake --build .
+```
+The `cpr` package in Conan is kept up to date by Conan contributors. If the version is out of date, please [create an issue or pull request](https://github.com/conan-io/conan-center-index) on the `conan-center-index` repository.

+# The output .so file lacks the soname number which we currently have within the lib/Makefile.am file
+# Add full (4 or 5 libs) SSL support
+# Add INSTALL target (EXTRA_DIST variables in Makefile.am may be moved to Makefile.inc so that CMake/CPack is aware of what's to include).
+# Check on all possible platforms
+# Test with as many configurations possible (With or without any option)
+# Create scripts that help keeping the CMake build system up to date (to reduce maintenance). According to Tetetest:
+#  - lists of headers that 'configure' checks for;
+#  - curl-specific tests (the ones that are in m4/curl-*.m4 files);
+#  - (most obvious thing:) curl version numbers.
+# Add documentation subproject
+#
+# To check:
+# (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not.
+# (From Daniel Stenberg) The gcc command line use neither -g nor any -O options. As a developer, I also treasure our configure scripts's --enable-debug option that sets a long range of "picky" compiler options.

+
+GIT-INFO
+
+This file is only present in git - never in release archives. It contains
+information about other files and things that the git repository keeps in its
+inner sanctum.
+
+To build in environments that support configure, after having extracted
+everything from git, do this:
+
+./buildconf
+./configure
+make
+
+  Daniel uses a ./configure line similar to this for easier development:
+
+  ./configure --disable-shared --enable-debug --enable-maintainer-mode
+
+In environments that don't support configure (i.e. Microsoft), do this:
+
+buildconf.bat
+
+
+REQUIREMENTS
+
+ For buildconf (not buildconf.bat) to work, you need the following software
+installed:
+
+ o autoconf 2.57  (or later)
+ o automake 1.7   (or later)
+ o libtool  1.4.2 (or later)
+ o GNU m4 (required by autoconf)
+
+ o nroff + perl
+
+   If you don't have nroff and perl and you for some reason don't want to
+   install them, you can rename the source file src/tool_hugehelp.c.cvs to
+   src/tool_hugehelp.c and avoid having to generate this file. This will
+   give you a stubbed version of the file that doesn't contain actual content.

+#Filename   : Makefile.vxworks
+#Description: makefile to be used in order to compile libcurl for VxWoorks 6.3.
+#
+#How to use:
+#             1. Adjust environment variables at the file beginning
+#             2. Open the Command Prompt window and change directory ('cd')
+#                into the 'lib' folder
+#             3. Add <CYGWIN>/bin folder to the PATH environment variable
+#                For example type 'set PATH=C:/embedded/cygwin/bin;%PATH%'
+#             4. Build the library by typing 'make -f ./Makefile.vxworks'
+#             As a result the libcurl.a should be created in the 'lib' folder.
+#             To clean package use 'make -f ./Makefile.vxworks clean'
+#Requirements:
+#             1. WinXP machine
+#             2. Full CYGWIN installation (open source) with GNU make version
+#                v3.78 or higher
+#             3. WindRiver Workbench with vxWorks 6.3 (commercial)

+         talking to a pool of DNS servers that can only successfully resolve
+         IPv4 address, for example).
+
+         It's also possible that the other request could always just take
+         longer because it needs more time or only the second DNS server can
+         fulfill it successfully.  But, to align with the philosophy of Happy
+         Eyeballs, we don't want to wait _too_ long or users will think
+         requests are slow when IPv6 lookups don't actually work (but IPv4 ones
+         do).
+
+         So, now that we have a usable answer (some IPv4 addresses, some IPv6
+         addresses, or "no such domain"), we start a timeout for the remaining
+         pending responses.  Even though it is typical that this resolved
+         request came back quickly, that needn't be the case.  It might be that
+         this completing request didn't get a result from the first DNS server
+         or even the first round of the whole DNS server pool.  So it could
+         already be quite some time after we issued the DNS queries in the
+         first place.  Without modifying c-ares, we can't know exactly where in
+         its retry cycle we are.  We could guess based on how much time has
+         gone by, but it doesn't really matter.  Happy Eyeballs tells us that,
+         given usable information in hand, we simply don't want to wait "too
+         much longer" after we get a result.
+
+         We simply wait an additional amount of time equal to the default
+         c-ares query timeout.  That is enough time for a typical parallel
+         response to arrive without being "too long".  Even on a network
+         where one of the two types of queries is failing or timing out
+         constantly, this will usually mean we wait a total of the default
+         c-ares timeout (5 seconds) plus the round trip time for the successful
+         request, which seems bearable.  The downside is that c-ares might race
+         with us to issue one more retry just before we give up, but it seems
+         better to "waste" that request instead of trying to guess the perfect
+         timeout to prevent it.  After all, we don't even know where in the
+         c-ares retry cycle each request is.

+RECEIVING COOKIE INFORMATION
+============================
+
+struct CookieInfo *Curl_cookie_init(struct Curl_easy *data,
+                    const char *file, struct CookieInfo *inc, bool newsession);
+
+        Inits a cookie struct to store data in a local file. This is always
+        called before any cookies are set.
+
+struct Cookie *Curl_cookie_add(struct Curl_easy *data,
+                 struct CookieInfo *c, bool httpheader, char *lineptr,
+                 const char *domain, const char *path);
+
+        The 'lineptr' parameter is a full "Set-cookie:" line as
+        received from a server.
+
+        The function need to replace previously stored lines that this new
+        line supersedes.
+
+        It may remove lines that are expired.
+
+        It should return an indication of success/error.
+
+
+SENDING COOKIE INFORMATION
+==========================
+
+struct Cookies *Curl_cookie_getlist(struct CookieInfo *cookie,
+                                    char *host, char *path, bool secure);
+
+        For a given host and path, return a linked list of cookies that
+        the client should send to the server if used now. The secure
+        boolean informs the cookie if a secure connection is achieved or
+        not.
+
+        It shall only return cookies that haven't expired.
+
+
+Example set of cookies:
+
+    Set-cookie: PRODUCTINFO=webxpress; domain=.fidelity.com; path=/; secure
+    Set-cookie: PERSONALIZE=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/ftgw; secure
+    Set-cookie: FidHist=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/; secure
+    Set-cookie: FidOrder=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/; secure
+    Set-cookie: DisPend=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/; secure
+    Set-cookie: FidDis=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/; secure
+    Set-cookie:
+    Session_Key@6791a9e0-901a-11d0-a1c8-9b012c88aa77=none;expires=Monday,

+ * Nasty internal details ahead...
+ *
+ * File curl_memory.h must be included by _all_ *.c source files
+ * that use memory related functions strdup, malloc, calloc, realloc
+ * or free, and given source file is used to build libcurl library.
+ * It should be included immediately before memdebug.h as the last files
+ * included to avoid undesired interaction with other memory function
+ * headers in dependent libraries.
+ *
+ * There is nearly no exception to above rule. All libcurl source
+ * files in 'lib' subdirectory as well as those living deep inside
+ * 'packages' subdirectories and linked together in order to build
+ * libcurl library shall follow it.
+ *
+ * File lib/strdup.c is an exception, given that it provides a strdup
+ * clone implementation while using malloc. Extra care needed inside
+ * this one.
+ *
+ * The need for curl_memory.h inclusion is due to libcurl's feature
+ * of allowing library user to provide memory replacement functions,
+ * memory callbacks, at runtime with curl_global_init_mem()
+ *
+ * Any *.c source file used to build libcurl library that does not
+ * include curl_memory.h and uses any memory function of the five
+ * mentioned above will compile without any indication, but it will
+ * trigger weird memory related issues at runtime.
+ *
+ * OTOH some source files from 'lib' subdirectory may additionally be
+ * used directly as source code when using some curlx_ functions by
+ * third party programs that don't even use libcurl at all. When using
+ * these source files in this way it is necessary these are compiled
+ * with CURLX_NO_MEMORY_CALLBACKS defined, in order to ensure that no
+ * attempt of calling libcurl's memory callbacks is done from code
+ * which can not use this machinery.
+ *
+ * Notice that libcurl's 'memory tracking' system works chaining into
+ * the memory callback machinery. This implies that when compiling
+ * 'lib' source files with CURLX_NO_MEMORY_CALLBACKS defined this file
+ * disengages usage of libcurl's 'memory tracking' system, defining
+ * MEMDEBUG_NODEFINES and overriding CURLDEBUG purpose.
+ *
+ * CURLX_NO_MEMORY_CALLBACKS takes precedence over CURLDEBUG. This is
+ * done in order to allow building a 'memory tracking' enabled libcurl
+ * and at the same time allow building programs which do not use it.
+ *
+ * Programs and libraries in 'tests' subdirectories have specific
+ * purposes and needs, and as such each one will use whatever fits
+ * best, depending additionally whether it links with libcurl or not.
+ *
+ * Caveat emptor. Proper curlx_* separation is a work in progress
+ * the same as CURLX_NO_MEMORY_CALLBACKS usage, some adjustments may
+ * still be required. IOW don't use them yet, there are sharp edges.

+ * FormAdd()
+ *
+ * Stores a formpost parameter and builds the appropriate linked list.

+ * Has two principal functionalities: using files and byte arrays as
+ * post parts. Byte arrays are either copied or just the pointer is stored
+ * (as the user requests) while for files only the filename and not the
+ * content is stored.
+ *
+ * While you may have only one byte array for each name, multiple filenames
+ * are allowed (and because of this feature CURLFORM_END is needed after
+ * using CURLFORM_FILE).
+ *
+ * Examples:
+ *
+ * Simple name/value pair with copied contents:
+ * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
+ * CURLFORM_COPYCONTENTS, "value", CURLFORM_END);
+ *
+ * name/value pair where only the content pointer is remembered:
+ * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
+ * CURLFORM_PTRCONTENTS, ptr, CURLFORM_CONTENTSLENGTH, 10, CURLFORM_END);
+ * (if CURLFORM_CONTENTSLENGTH is missing strlen () is used)
+ *
+ * storing a filename (CONTENTTYPE is optional!):
+ * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
+ * CURLFORM_FILE, "filename1", CURLFORM_CONTENTTYPE, "plain/text",
+ * CURLFORM_END);
+ *
+ * storing multiple filenames:
+ * curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
+ * CURLFORM_FILE, "filename1", CURLFORM_FILE, "filename2", CURLFORM_END);
+ *
+ * Returns:
+ * CURL_FORMADD_OK             on success
+ * CURL_FORMADD_MEMORY         if the FormInfo allocation fails
+ * CURL_FORMADD_OPTION_TWICE   if one option is given twice for one Form
+ * CURL_FORMADD_NULL           if a null pointer was given for a char
+ * CURL_FORMADD_MEMORY         if the allocation of a FormInfo struct failed
+ * CURL_FORMADD_UNKNOWN_OPTION if an unknown option was used
+ * CURL_FORMADD_INCOMPLETE     if the some FormInfo is not complete (or error)
+ * CURL_FORMADD_MEMORY         if a HttpPost struct cannot be allocated
+ * CURL_FORMADD_MEMORY         if some allocation for string copying failed.

+ * hostip.c explained
+ * ==================
+ *
+ * The main COMPILE-TIME DEFINES to keep in mind when reading the host*.c
+ * source file are these:
+ *
+ * CURLRES_IPV6 - this host has getaddrinfo() and family, and thus we use
+ * that. The host may not be able to resolve IPv6, but we don't really have to
+ * take that into account. Hosts that aren't IPv6-enabled have CURLRES_IPV4
+ * defined.
+ *
+ * CURLRES_ARES - is defined if libcurl is built to use c-ares for
+ * asynchronous name resolves. This can be Windows or *nix.
+ *
+ * CURLRES_THREADED - is defined if libcurl is built to run under (native)
+ * Windows, and then the name resolve will be done in a new thread, and the
+ * supported API will be the same as for ares-builds.
+ *
+ * If any of the two previous are defined, CURLRES_ASYNCH is defined too. If
+ * libcurl is not built to use an asynchronous resolver, CURLRES_SYNCH is
+ * defined.
+ *
+ * The host*.c sources files are split up like this:
+ *
+ * hostip.c   - method-independent resolver functions and utility functions
+ * hostasyn.c - functions for asynchronous name resolves
+ * hostsyn.c  - functions for synchronous name resolves
+ * hostip4.c  - IPv4 specific functions
+ * hostip6.c  - IPv6 specific functions
+ *
+ * The two asynchronous name resolver backends are implemented in:
+ * asyn-ares.c   - functions for ares-using name resolves
+ * asyn-thread.c - functions for threaded name resolves
+
+ * The hostip.h is the united header file for all this. It defines the
+ * CURLRES_* defines based on the config*.h and curl_setup.h defines.

+ * make an average of 1000 nodes in each list to run through. I upped that to
+ * 97 slots (I believe a prime is suitable) and noticed a significant speed

+
+     The "-no_ticket" option was introduced in Openssl0.9.8j. It's a flag to
+     disable "rfc4507bis session ticket support".  rfc4507bis was later turned
+     into the proper RFC5077 it seems: https://tools.ietf.org/html/rfc5077
+
+     The enabled extension concerns the session management. I wonder how often
+     libcurl stops a connection and then resumes a TLS session. also, sending
+     the session data is some overhead. .I suggest that you just use your
+     proposed patch (which explicitly disables TICKET).
+
+     If someone writes an application with libcurl and openssl who wants to
+     enable the feature, one can do this in the SSL callback.

+
+     Due to CVE-2010-4180, option SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG has
+     become ineffective as of OpenSSL 0.9.8q and 1.0.0c. In order to mitigate
+     CVE-2010-4180 when using previous OpenSSL versions we no longer enable
+     this option regardless of OpenSSL version and SSL_OP_ALL definition.
+
+     OpenSSL added a work-around for a SSL 3.0/TLS 1.0 CBC vulnerability
+     (https://www.openssl.org/~bodo/tls-cbc.txt). In 0.9.6e they added a bit to
+     SSL_OP_ALL that _disables_ that work-around despite the fact that
+     SSL_OP_ALL is documented to do "rather harmless" workarounds. In order to
+     keep the secure work-around, the SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS bit

+# SYNOPSIS
+#
+#   AX_COMPILE_CHECK_SIZEOF(TYPE [, HEADERS [, EXTRA_SIZES...]])
+#
+# DESCRIPTION
+#
+#   This macro checks for the size of TYPE using compile checks, not run
+#   checks. You can supply extra HEADERS to look into. the check will cycle
+#   through 1 2 4 8 16 and any EXTRA_SIZES the user supplies. If a match is
+#   found, it will #define SIZEOF_`TYPE' to that value. Otherwise it will
+#   emit a configure time error indicating the size of the type could not be
+#   determined.
+#
+#   The trick is that C will not allow duplicate case labels. While this is
+#   valid C code:
+#
+#     switch (0) case 0: case 1:;
+#
+#   The following is not:
+#
+#     switch (0) case 0: case 0:;
+#
+#   Thus, the AC_TRY_COMPILE will fail if the currently tried size does not
+#   match.
+#
+#   Here is an example skeleton configure.in script, demonstrating the
+#   macro's usage:
+#
+#     AC_PROG_CC
+#     AC_CHECK_HEADERS(stddef.h unistd.h)
+#     AC_TYPE_SIZE_T
+#     AC_CHECK_TYPE(ssize_t, int)

+dnl Public macro.
+dnl
+dnl This macro embeds shell code into configure script
+dnl that amends, at configure runtime, the distclean
+dnl and maintainer-clean targets of Makefiles located
+dnl in all subdirs given in the mandatory white-space
+dnl separated list argument.
+dnl
+dnl Embedding only takes place when using automake 1.14
+dnl or newer, otherwise amending code is not included
+dnl in generated configure script.
+dnl
+dnl distclean and maintainer-clean targets are modified
+dnl to avoid unconditional removal of dependency subdirs
+dnl which triggers distclean and maintainer-clean errors
+dnl when using automake 'subdir-objects' option along
+dnl with per-target objects and source files existing in
+dnl multiple subdirs used for different build targets.
+dnl
+dnl New behavior first removes each dependency tracking
+dnl file independently, and only removes each dependency
+dnl subdir when it finds out that it no longer holds any
+dnl dependency tracking file.
+dnl
+dnl When configure option --disable-dependency-tracking
+dnl is used no amending takes place given that there are
+dnl no dependency tracking files.

+dnl
+dnl These basic checks are intended to be placed and
+dnl executed as early as possible in the resulting

+dnl
+dnl This macro may be used directly, or indirectly
+dnl when using other macros that AC_REQUIRE it such

+dnl

+# Google Android makefile for curl and libcurl
+#
+# This file can be used when building curl using the full Android source
+# release or the NDK. Most users do not want or need to do this; please
+# instead read the Android section in docs/INSTALL for alternate
+# methods.
+#
+# Place the curl source (including this makefile) into external/curl/ in the
+# Android source tree.  Then build them with 'make curl' or just 'make libcurl'
+# from the Android root. Tested with Android versions 1.5, 2.1-2.3
+#
+# Note: you must first create a curl_config.h file by running configure in the
+# Android environment. The only way I've found to do this is tricky. Perform a
+# normal Android build with libcurl in the source tree, providing the target
+# "showcommands" to make. The build will eventually fail (because curl_config.h
+# doesn't exist yet), but the compiler commands used to build curl will be
+# shown. Now, from the external/curl/ directory, run curl's normal configure
+# command with flags that match what Android itself uses. This will mean
+# putting the compiler directory into the PATH, putting the -I, -isystem and
+# -D options into CPPFLAGS, putting the -W, -m, -f, -O and -nostdlib options
+# into CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the
+# path to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o.
+# Remember that the paths must be absolute since you will not be running
+# configure from the same directory as the Android make.  The normal
+# cross-compiler options must also be set. Note that the -c, -o, -MD and
+# similar flags must not be set.
+#
+# To see all the LIBS options, you'll need to do the "showcommands" trick on an
+# executable that's already buildable and watch what flags Android uses to link
+# it (dhcpcd is a good choice to watch). You'll also want to add -L options to
+# LIBS that point to the out/.../obj/lib/ and out/.../obj/system/lib/
+# directories so that additional libraries can be found and used by curl.
+#
+# The end result will be a configure command that looks something like this
+# (the environment variable A is set to the Android root path which makes the
+# command shorter):
+#
+#  A=`realpath ../..` && \
+#  PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \
+#  ./configure --host=arm-linux CC=arm-eabi-gcc \
+#  CPPFLAGS="-I $A/system/core/include ..." \
+#  CFLAGS="-nostdlib -fno-exceptions -Wno-multichar ..." \
+#  LIBS="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/lib/gcc/arm-eabi/X\
+#  /interwork/libgcc.a ..."
+#

+# into the right place (but see the note about this below).

+
+Implementation notes:
+
+  This is a true OS/400 implementation, not a PASE implementation (for PASE,
+use AIX implementation).
+
+  The biggest problem with OS/400 is EBCDIC. Libcurl implements an internal
+conversion mechanism, but it has been designed for computers that have a
+single native character set. OS/400 default native character set varies
+depending on the country for which it has been localized. And more, a job
+may dynamically alter its "native" character set.
+  Several characters that do not have fixed code in EBCDIC variants are
+used in libcurl strings. As a consequence, using the existing conversion
+mechanism would have lead in a localized binary library - not portable across
+countries.
+  For this reason, and because libcurl was originally designed for ASCII based
+operating systems, the current OS/400 implementation uses ASCII as internal
+character set. This has been accomplished using the QADRT library and
+include files, a C and system procedures ASCII wrapper library. See IBM QADRT
+description for more information.
+  This then results in libcurl being an ASCII library: any function string
+argument is taken/returned in ASCII and a C/C++ calling program built around
+QADRT may use libcurl functions as on any other platform.
+  QADRT does not define ASCII wrappers for all C/system procedures: the
+OS/400 configuration header file and an additional module (os400sys.c) define
+some more of them, that are used by libcurl and that QADRT left out.
+  To support all the different variants of EBCDIC, non-standard wrapper
+procedures have been added to libcurl on OS/400: they provide an additional
+CCSID (numeric Coded Character Set ID specific to OS/400) parameter for each
+string argument. String values passed to callback procedures are NOT converted,
+so text gathered this way is (probably !) ASCII.
+
+  Another OS/400 problem comes from the fact that the last fixed argument of a
+vararg procedure may not be of type char, unsigned char, short or unsigned
+short. Enums that are internally implemented by the C compiler as one of these
+types are also forbidden. Libcurl uses enums as vararg procedure tagfields...
+Happily, there is a pragma forcing enums to type "int". The original libcurl
+header files are thus altered during build process to use this pragma, in
+order to force libcurl enums of being type int (the pragma disposition in use
+before inclusion is restored before resuming the including unit compilation).
+
+  Secure socket layer is provided by the IBM GSKit API: unlike other SSL
+implementations, GSKit is based on "certificate stores" or keyrings
+rather than individual certificate/key files. Certificate stores, as well as
+"certificate labels" are managed by external IBM-defined applications.
+  There are two ways to specify an SSL context:
+- By an application identifier.
+- By a keyring file pathname and (optionally) certificate label.
+  To identify an SSL context by application identifier, use option
+SETOPT_SSLCERT to specify the application identifier.
+  To address an SSL context by keyring and certificate label, use CURLOPT_CAINFO
+to set-up the keyring pathname, CURLOPT_SSLCERT to define the certificate label
+(omitting it will cause the default certificate in keyring to be used) and
+CURLOPT_KEYPASSWD to give the keyring password. If SSL is used without
+defining any of these options, the default (i.e.: system) keyring is used for
+server certificate validation.
+
+  Non-standard EBCDIC wrapper prototypes are defined in an additional header
+file: ccsidcurl.h. These should be self-explanatory to an OS/400-aware
+designer. CCSID 0 can be used to select the current job's CCSID.
+  Wrapper procedures with variable arguments are described below:
+
+_ curl_easy_setopt_ccsid()
+  Variable arguments are a string pointer and a CCSID (unsigned int) for
+options:
+        CURLOPT_ABSTRACT_UNIX_SOCKET
+        CURLOPT_ALTSVC
+        CURLOPT_CAINFO

+        CURLOPT_PINNEDPUBLICKEY
+        CURLOPT_PRE_PROXY
+        CURLOPT_PROXY

+        CURLOPT_USERAGENT
+        CURLOPT_USERNAME
+        CURLOPT_USERPWD
+        CURLOPT_XOAUTH2_BEARER
+  Else it is the same as for curl_easy_setopt().
+  Note that CURLOPT_ERRORBUFFER is not in the list above, since it gives the
+address of an (empty) character buffer, not the address of a string.
+CURLOPT_POSTFIELDS stores the address of static binary data (of type void *) and
+thus is not converted. If CURLOPT_COPYPOSTFIELDS is issued after
+CURLOPT_POSTFIELDSIZE != -1, the data size is adjusted according to the
+CCSID conversion result length.
+
+_ curl_formadd_ccsid()
+  In the variable argument list, string pointers should be followed by a (long)
+CCSID for the following options:
+        CURLFORM_FILENAME
+        CURLFORM_CONTENTTYPE
+        CURLFORM_BUFFER
+        CURLFORM_FILE
+        CURLFORM_FILECONTENT
+        CURLFORM_COPYCONTENTS
+        CURLFORM_COPYNAME
+        CURLFORM_PTRNAME
+  If taken from an argument array, an additional array entry must follow each
+entry containing one of the above option. This additional entry holds the CCSID
+in its value field, and the option field is meaningless.
+  It is not possible to have a string pointer and its CCSID across a function
+parameter/array boundary.
+  Please note that CURLFORM_PTRCONTENTS and CURLFORM_BUFFERPTR are considered
+unconvertible strings and thus are NOT followed by a CCSID.
+
+_ curl_easy_getinfo_ccsid()
+  The following options are followed by a 'char * *' and a CCSID. Unlike
+curl_easy_getinfo(), the value returned in the pointer should be freed after
+use:
+        CURLINFO_EFFECTIVE_URL
+        CURLINFO_CONTENT_TYPE
+        CURLINFO_FTP_ENTRY_PATH
+        CURLINFO_REDIRECT_URL
+        CURLINFO_PRIMARY_IP
+        CURLINFO_RTSP_SESSION_ID
+        CURLINFO_LOCAL_IP
+        CURLINFO_SCHEME
+  Likewise, the following options are followed by a struct curl_slist * * and a
+CCSID.
+        CURLINFO_SSL_ENGINES
+        CURLINFO_COOKIELIST
+Lists returned should be released with curl_slist_free_all() after use.
+  Option CURLINFO_CERTINFO is followed by a struct curl_certinfo * * and a
+CCSID. Returned structures should be free'ed using curl_certinfo_free_all()
+after use.
+  Other options are processed like in curl_easy_getinfo().
+
+_ curl_pushheader_bynum_cssid() and curl_pushheader_byname_ccsid()
+  Although the prototypes are self-explanatory, the returned string pointer
+should be freed after use, as opposite to the non-ccsid versions of these
+procedures.
+  Please note that HTTP2 is not (yet) implemented on OS/400, thus these
+functions will always return NULL.
+
+
+  Standard compilation environment does support neither autotools nor make;
+in fact, very few common utilities are available. As a consequence, the
+config-os400.h has been coded manually and the compilation scripts are
+a set of shell scripts stored in subdirectory packages/OS400.
+
+  The "curl" command and the test environment are currently not supported on
+OS/400.
+
+
+Protocols currently implemented on OS/400:
+_ DICT
+_ FILE
+_ FTP
+_ FTPS
+_ FTP with secure transmission
+_ GOPHER
+_ HTTP
+_ HTTPS
+_ IMAP
+_ IMAPS
+_ IMAP with secure transmission
+_ LDAP
+_ POP3
+_ POP3S
+_ POP3 with secure transmission
+_ RTSP
+_ SCP if libssh2 is enabled
+_ SFTP if libssh2 is enabled
+_ SMTP
+_ SMTPS
+_ SMTP with secure transmission
+_ TELNET
+_ TFTP
+
+
+
+Compiling on OS/400:
+
+  These instructions targets people who knows about OS/400, compiling, IFS and
+archive extraction. Do not ask questions about these subjects if you're not
+familiar with.
+
+_ As a prerequisite, QADRT development environment must be installed.
+_ If data compression has to be supported, ZLIB development environment must
+  be installed.
+_ Likewise, if SCP and SFTP protocols have to be compiled in, LIBSSH2
+  developent environment must be installed.
+_ Install the curl source directory in IFS. Do NOT install it in the
+  installation target directory (which defaults to /curl).
+_ Enter shell (QSH)
+_ Change current directory to the curl installation directory
+_ Change current directory to ./packages/OS400
+_ Edit file iniscript.sh. You may want to change tunable configuration
+  parameters, like debug info generation, optimisation level, listing option,
+  target library, ZLIB/LIBSSH2 availability and location, etc.
+_ Copy any file in the current directory to makelog (i.e.:
+  cp initscript.sh makelog): this is intended to create the makelog file with
+  an ASCII CCSID!
+_ Enter the command "sh makefile.sh > makelog 2>&1'
+_ Examine the makelog file to check for compilation errors.
+
+  Leaving file initscript.sh unchanged, this will produce the following OS/400
+objects:
+_ Library CURL. All other objects will be stored in this library.
+_ Modules for all libcurl units.
+_ Binding directory CURL_A, to be used at calling program link time for
+  statically binding the modules (specify BNDSRVPGM(QADRTTS QGLDCLNT QGLDBRDR)
+  when creating a program using CURL_A).
+_ Service program CURL.<soname>, where <soname> is extracted from the
+  lib/Makefile.am VERSION variable. To be used at calling program run-time
+  when this program has dynamically bound curl at link time.
+_ Binding directory CURL. To be used to dynamically bind libcurl when linking a
+  calling program.
+_ Source file H. It contains all the include members needed to compile a C/C++
+  module using libcurl, and an ILE/RPG /copy member for support in this
+  language.
+_ Standard C/C++ libcurl include members in file H.
+_ CCSIDCURL member in file H. This defines the non-standard EBCDIC wrappers for
+  C and C++.
+_ CURL.INC member in file H. This defines everything needed by an ILE/RPG
+  program using libcurl.
+_ LIBxxx modules and programs. Although the test environment is not supported
+  on OS/400, the libcurl test programs are compiled for manual tests.
+_ IFS directory /curl/include/curl containing the C header files for IFS source
+  C/C++ compilation and curl.inc.rpgle for IFS source ILE/RPG compilation.
+
+
+
+Special programming consideration:
+
+QADRT being used, the following points must be considered:
+_ If static binding is used, service program QADRTTS must be linked too.
+_ The EBCDIC CCSID used by QADRT is 37 by default, NOT THE JOB'S CCSID. If
+  another EBCDIC CCSID is required, it must be set via a locale through a call
+  to setlocale_a (QADRT's setlocale() ASCII wrapper) with category LC_ALL or
+  LC_CTYPE, or by setting environment variable QADRT_ENV_LOCALE to the locale
+  object path before executing the program.
+_ Do not use original source include files unless you know what you are doing.
+  Use the installed members instead (in /QSYS.LIB/CURL.LIB/H.FILE and
+  /curl/include/curl).
+
+
+
+ILE/RPG support:
+
+  Since 95% of the OS/400 programmers use ILE/RPG exclusively, a definition
+  /INCLUDE member is provided for this language. To include all libcurl
+  definitions in an ILE/RPG module, line
+
+     h bnddir('CURL/CURL')
+
+must figure in the program header, and line
+
+     d/include curl/h,curl.inc
+
+in the global data section of the module's source code.
+
+  No vararg procedure support exists in ILE/RPG: for this reason, the following
+considerations apply:
+_ Procedures curl_easy_setopt_long(), curl_easy_setopt_object(),
+  curl_easy_setopt_function() and curl_easy_setopt_offset() are all alias
+  prototypes to curl_easy_setopt(), but with different parameter lists.
+_ Procedures curl_easy_getinfo_string(), curl_easy_getinfo_long(),
+  curl_easy_getinfo_double(), curl_easy_getinfo_slist(),
+  curl_easy_getinfo_ptr(), curl_easy_getinfo_socket() and
+  curl_easy_getinfo_off_t() are all alias prototypes to curl_easy_getinfo(),
+  but with different parameter lists.
+_ Procedures curl_multi_setopt_long(), curl_multi_setopt_object(),
+  curl_multi_setopt_function() and curl_multi_setopt_offset() are all alias
+  prototypes to curl_multi_setopt(), but with different parameter lists.
+_ The prototype of procedure curl_formadd() allows specifying a pointer option
+  and the CURLFORM_END option. This makes possible to use an option array
+  without any additional definition. If some specific incompatible argument
+  list is used in the ILE/RPG program, the latter must define a specialised
+  alias. The same applies to curl_formadd_ccsid() too.
+
+  Since RPG cannot cast a long to a pointer, procedure curl_form_long_value()
+is provided for that purpose: this allows storing a long value in the curl_forms
+array.

+PACKAGES
+
+ This directory and all its subdirectories are for special package
+information, template, scripts and docs. The files herein should be of use for
+those of you who want to package curl in a binary or source format using one
+of those custom formats.
+
+ The hierarchy for these directories is something like this:
+
+   packages/[OS]/[FORMAT]/
+
+ Currently, we have Win32 and Linux for [OS]. There might be different formats
+for the same OS so for Linux we have RPM as format.
+
+ We might need to add some differentiation for CPU as well, as there is
+Linux-RPMs for several CPUs. However, it might not be necessary since the
+packaging should be pretty much the same no matter what CPU that is used.
+
+ For each unique OS-FORMAT pair, there's a directory to "fill"! I'd like to
+see a single README with as much details as possible, and then I'd like some
+template files for the package process.

+$! Backup save sets are the only storage format that I can expect a

+$! The make_pcsi_kit_name.com needs to be run before this procedure to
+$! properly name the files that will be created.
+$!
+$! This file is created from a template file for the purpose of making it
+$! easier to port Unix code, particularly open source code to VMS.
+$! Therefore permission is freely granted for any use.

+$! Build the *.pcsi$text file in the following sections:
+$!   Required software dependencies.
+$!   install/upgrade/postinstall steps.
+$!      1. Duplicate filenames need an alias procedure. (N/A for curl)
+$!      2. ODS-5 filenames need an alias procedure. (N/A for curl)
+$!      3. Special alias links for executables (curl. -> curl.exe)
+$!         if a lot, then an alias procedure is needed.
+$!      4. Rename the files to lowercase.
+$!   Move Release Notes to destination
+$!   Source kit option
+$!   Create directory lines
+$!   Add file lines for curl.
+$!   Add Link alias procedure file (N/A for curl)
+$!   Add [.SYS$STARTUP]curl_startup file
+$!   Add Release notes file.
+$!
+$! The file PCSI_GNV_CURL_FILE_LIST.TXT is read in to get the files other
+$! than the release notes file and the source backup file.
+$!
+$! The PCSI system can really only handle ODS-2 format filenames and
+$! assumes that there is only one source directory.  It also assumes that
+$! all destination files with the same name come from the same source file.
+$! Fortunately CURL does not trip most of these issues, so those steps
+$! above are marked N/A.
+$!
+$! A rename action section is needed to make sure that the files are
+$! created in the GNV$GNU: in the correct case, and to create the alias
+$! link [usr.bin]curl. for [usr.bin]curl.exe.

+$! BUILD_VMS.COM
+$!
+$! I've taken the original build_vms.com, supplied by Nico Baggus, if
+$! memory serves me correctly, and made some modifications.
+$!
+$! SSL support is controlled by logical names.  If SSL$INCLUDE is
+$! defined, then it is assumed that HP's SSL product has been installed.
+$! If OPENSSL is defined, but SSL$INCLUDE is not, then OpenSSL will be
+$! used.  If neither logical name is defined, then SSL support will not
+$! be compiled/linked in.  Command-line options NOHPSSL and NOSSL can be
+$! specified to override the automatic SSL selection.
+$!
+$! Command-line Options:
+$!
+$!    CLEAN     Delete product files for this host architecture.  (No
+$!              build done.)
+$!    CLEAN_ALL Delete product files for all host architectures.  (No
+$!              build done.)
+$!
+$!    64        Compile with 64-bit pointers.
+$!              Note, you must match the pointer size that the OpenSSL
+$!              shared image expects.
+$!              Currently curl is not building properly with 64 bit pointers
+$!              on VMS because it is trying to cast pointers to 32 bit
+$!              integers and some OpenVMS library routines called by curl
+$!              do not yet support 64 bit pointers.
+$!    CCQUAL=x  Add "x" to the C compiler qualifiers.
+$!              Default qualifiers are:
+$!                  /standard=relaxed
+$!                  /names=(as_is, shortened)
+$!                  /repository=[.'arch']
+$!                  /nested_include_directory=none
+$!                  /define=(_LARGEFILE=1,_USE_STD_STAT=1) (non-vax)
+$!                  /float=ieee/ieee_mode=denorm_results (non-vax)
+$!    DEBUG     Compile debug and nooptimize
+$!              Alpha/IA64 always compiles /debug.
+$!              Always link a debug image.
+$!    NOIEEE    Do not use IEEE floating point.  (Alpha/I64)
+$!              VAX must always use DFLOAT
+$!    NOLARGE   Disable large-file support if large file support available.
+$!              (Non-VAX, VMS >= V7.2.)
+$!    NOLDAP    Disable LDAP support if LDAP is available.
+$!    NOKERBEROS   Disable Kerberos support if Kerberos is available.
+$!    LIST      Create C compiler listings and linker maps.
+$!                 /list/show=(expan,includ)/machine
+$!    FULLLIST  Full detailed listing.
+$!                 /list/show=(all, nomessages)/machine
+$!    NOHPSSL   Don't use HP SSL, even if available.
+$!              Note, you must match the pointer size that the OpenSSL
+$!              shared image expects.  This procedure will select the
+$!              correct HP OpenSSL image.
+$!    NOSSL     Don't use any SSL, even if available.
+$!    OSSLOLB   Use OpenSSL object libraries (.OLB), even if shared
+$!              images (.EXE) are available.
+$!    NOZLIB    Don't use GNV$ZLIB shared image even if available.
+$!    REALCLEAN Delete product files for all host architectures.  (No
+$!              build done.)  Alias for CLEAN_ALL
+$!
+$! DCL Symbols:
+$!
+$!    CURL_CCDEFS="c_macro_1=value1 [, c_macro_2=value2 [...]]"
+$!              Compile with these additional C macros defined.
+$!
+$! Revisions:
+$!
+$!  2-DEC-2003, MSK, the "original" version.
+$!                   It works for me.  Your mileage may vary.
+$! 13-JAN-2004, MSK, moved this procedure to the [.packages.vms] directory
+$!                   and updated it to do hardware dependent builds.
+$! 29-JAN-2004, MSK, moved logical defines into defines.com
+$!  6-FEB-2004, MSK, put in various SSL support bits
+$!  9-MAR-2004, MSK, the config-vms.h* files are now copied to the lib and
+$!                   src directories as curl_config.h.
+$! 15-MAR-2004, MSK, All of the curlmsg*.* files have also been moved to
+$!                   this build directory.  They will be copied to the src
+$!                   directory before build.  The .msg file will be compiled
+$!                   to get the .obj for messages, but the .h and .sdl files
+$!                   are not automatically created since they partly rely on
+$!                   the freeware SDL tool.
+$!  8-FEB-2005, MSK, merged the two config-vms.h* files into one that uses
+$!                   USE_SSLEAY to define if the target has SSL support built
+$!                   in.  Changed the cc/define parameter accordingly.
+$! 11-FEB-2005, MSK, If [--.LIB]AMIGAOS.C and NWLIB.C are there, rename them
+$! 23-MAR-2005, MSK, relocated cc_qual define so that DEBUG option would work
+$! 25-APR-2007, STL, allow compilation in 64-bit mode.
+$! 13-DEC-2009. SMS, Changed to skip unwanted source files without
+$!                   renaming the original files.
+$!                   Eliminated needless, persistent logical names.
+$!                   Added CURL_CCDEFS DCL symbol for user-specified C
+$!                   macro definitions.
+$!                   Added CLEAN and CLEAN_ALL options.
+$!                   Added CCQUAL option for user-specified C compiler
+$!                   qualifiers.
+$!                   Added IEEE option for IEEE floating point (Alpha).
+$!                   Added LARGE option for large-file support.
+$!                   Added OSSLOLB option, and support for OpenSSL
+$!                   shared images.
+$!                   Changed to put listing and map files into lisdir:.
+$!                   Changed to avoid case confusion on ODS5 disks.
+$!                   Added more default dev:[dir] save+restore.
+$!                   Moved remaining "defines.com" code (back) into
+$!                   here, eliminating the hard-coded OpenSSL nonsense.
+$!                   Changed to use F$GETSYI("ARCH_NAME") (or
+$!                   equivalent) to name architecture-specific product
+$!                   file destination directory, and to create the
+$!                   directory if needed (obviating inclusion of these
+$!                   directories and dummy files in the distribution
+$!                   kit).
+$!                   Changed the "compile" subroutine to break the CC
+$!                   command across multiple lines to avoid DCL
+$!                   line-too-long problems.
+$!                   Changed "vo_c" messages to show the CC qualifiers
+$!                   once, not with every compile command.
+$! 01-Jan-2013  J. Malmberg
+$!                   VMS build procedures need to be able to work with
+$!                   the default set to a search list, with created or
+$!                   modified files only in the first member of the search
+$!                   list.
+$!                   Whitespace change to be more compatible with current
+$!                   practices.
+$!                   One pass option parsing instead of loop.
+$!                   GNV ZLIB shared image support.
+$!                   KERBEROS support where available.
+$!                   LDAP default to on where available
+$!                   LARGEFILE default to on where available
+$!                   IEEE float default to on where available.
+$!                   Generate the curl_config.h file from system inspection.
+$!                   Linker finds ldap with out option file.
+$! 13-Mar-2013, Tom Grace
+$!                   Added missing slash in cc_full_list.
+$!                   Removed unwanted extra quotes inside symbol tool_main
+$!                   for non-VAX architectures that triggered link failure.
+$!                   Replaced curl_sys_inc with sys_inc.
+$! 19-Mar-2013, John Malmberg
+$!                   symbol tool_main needs to be quoted when parse style is
+$!                   set to extended in versions of VMS greater than 7.3-1.
+$!                   Remove curlbuild.h generation as it should be pre-built
+$!                   in the curl release or daily tarball.
+$! 12-Jul-2013, John Malmberg
+$!                   Adjust to find and use ZLIB from the Jean-Francois
+$!                   Pieronne shared image and newer GNV ZLIB kit that
+$!                   is upward compatible with Jean-Francois's kit.
+$!                   Remove tabs from file.
+$!                   Fixed DCL formatting as follows:
+$!                      * Labels have no space after leading $.
+$!                      * 1 space after $ for first level.
+$!                      * 3 spaces after $ for second level.  Line start + 4.
+$!                      * 7 spaces after $ for third level.  Line start + 8.
+$!                      * Each level after that indents 4 characters.
+$!                      * then/else/endif same indentation as if statement.
+$! 17-Nov-2014, Michael Steve
+$!                   Modified build to handle new location of the VTLS lib
+$!                   source within zip archive. Not a pretty fix.

+$! This procedure compares the files in two directories and reports the
+$! differences.  It is customized for the vmsports repository layout.
+$!
+$! It needs to be customized to the local site directories.
+$!
+$! This is used by me for these purposes:
+$!     1. Compare the original source of a project with an existing
+$!        VMS port.
+$!     2. Compare the checked out repository of a project with the
+$!        the local working copy to make sure they are in sync.
+$!     3. Keep a copy directory up to date.  The third is needed by
+$!        me because VMS Backup can create a saveset of files from a
+$!        NFS mounted volume.
+$!
+$! First the files in the original source directory which is assumed to be
+$! under source code control are compared with the copy directory.
+$!
+$! Then the files are are only in the copy directory are listed.
+$!
+$! The result will five diagnostics about of files:
+$!    1. Files that are not generation 1.
+$!    2. Files missing in the copy directory.
+$!    3. Files in the copy directory not in the source directory.
+$!    4. Files different from the source directory.
+$!    5. Files that VMS DIFF can not process.
+$!
+$! This needs to be run on an ODS-5 volume.
+$!
+$! If UPDATE is given as a second parameter, files missing or different in the
+$! copy directory will be updated.
+$!
+$! By default:
+$!    The directory src_root:[project_name] will be translated to something like
+$!    DISK:[dir.dir.reference.project_name] and this will be used
+$!    to calculate DISK:[dir.dir.vms_source.project_name] for the VMS specific
+$!    source directory.
+$!
+$!    The copy directory is vms_root:[project_name]
+$!    The UPDATE parameter is ignored.
+$!
+$!    This setting is used to make sure that the working vms directory
+$!    and the repository checkout directory have the same contents.
+$!
+$! If P1 is "SRCBCK" then this
+$!     The source directory tree is: src_root:[project_name]
+$!     The copy directory is src_root1:[project_name]
+$!
+$!   src_root1:[project_name] is used by me to work around that VMS backup will
+$!   not use NFS as a source directory so I need to make a copy.
+$!
+$!   This is to make sure that the backup save set for the unmodified
+$!   source is up to date.
+$!
+$!   If your repository checkout is not on an NFS mounted volume, you do not
+$!   need to use this option or have the logical name src_root1 defined.
+$!
+$! If P1 is "VMSBCK" then this changes the two directories:
+$!    The source directory is vms_root:[project_name]
+$!    The copy directory is vms_root1:[project_name]
+$!
+$!   vms_root:[project_name] is where I do the VMS specific edits.
+$!   vms_root1:[project_name] is used by me to work around that VMS backup will
+$!   not use NFS as a source directory so I need to make a copy.
+$!
+$!   This is to make sure that the backup save set for the unmodified
+$!   source is up to date.

+$!
+$! This procedure attempts to figure out how to build a config.h file
+$! for the current project.
+$!
+$! P1 specifies the config.h.in file or equivalent.  If it is not specified
+$! then this procedure will search for several common names of the file.
+$!
+$! The CONFIGURE shell script will be examined for hints and a few symbols
+$! but most of the tests will not produce valid results on OpenVMS.  Some
+$! will produce false positives and some will produce false negatives.
+$!
+$! It is easier to just read the config.h_in file and make up tests based
+$! on what is in it!
+$!
+$! This file will create an empty config_vms.h file if one does not exist.
+$! The config_vms.h is intended for manual edits to handle things that
+$! this procedure can not.
+$!
+$! The config_vms.h will be invoked by the resulting config.h file.
+$!
+$! This procedure knows about the DEC C RTL on the system it is on.
+$! Future versions may be handle the GNV, the OpenVMS porting library,
+$! and others.
+$!
+$! This procedure may not guess the options correctly for all architectures,
+$! and is a work in progress.

+
+Currently building Curl using GNV takes longer than building Curl via DCL.
+The GNV procedure actually uses the same configure and makefiles that
+Unix builds use.
+
+Building CURL on OpenVMS using GNV requires GNV V2.1-2 or the updated
+images that are available via anonymous FTP at encompasserve.org in the gnv
+directory.  It also requires the GNV Bash 4.2.45 kit as an update from the
+same location or from the sourceforge.net GNV project.
+
+The HP C 7.x compiler was used for building the GNV version.
+
+The source kits are provided in backup savesets inside of the PCSI install kit.
+
+Backup save sets are currently the only distribution medium that I can be
+sure is installed on a target VMS system that will correctly unpack files
+with extended character sets in them.  You may need to adjust the ownership
+of the restored files, since /Interchange/noconvert was not available at the
+time that this document was written.
+
+[gnv.common_src]curl_*_original_src.bck is the original source of the curl kit
+as provided by the curl project.  [gnv.vms_src]curl-*_vms_src.bck, if present,
+has the OpenVMS specific files that are used for building that are not yet in
+the curl source kits for that release distributed https://curl.se
+
+These backup savesets should be restored to different directory trees on
+an ODS-5 volume(s) which are referenced by concealed rooted logical names.
+
+SRC_ROOT: is for the source files common to all platforms.
+VMS_ROOT: is for the source files that are specific to OpenVMS.
+          Note, you should create the VMS_ROOT: directory tree even if it is
+          initially empty.  This is where you should put edits if you are
+          making changes.
+LCL_ROOT: is manually created to have the same base and sub-directories as
+          SRC_ROOT: and VMS_ROOT:
+
+The logical name REF_ROOT: may be defined to be a search list for
+VMS_ROOT:,SRC_ROOT:
+
+The logical name PRJ_ROOT: is defined to be a search list for
+LCL_ROOT:,VMS_ROOT:,SRC_ROOT:
+
+For the make install process to work, it must have write access to the
+directories referenced by the GNU: logical name.
+
+In future releases of GNV, and with GNV Bash 4.3.30 installed, this name
+should be GNV$GNU:
+
+As directly updating those directories would probably be disruptive to other
+users of the system and require elevated privilege, this can be handled by
+creating a separate directory tree to install into which can be referenced
+by the concealed rooted logical name new_gnu:.  A concealed logical name of
+OLD_GNU: can be set up to reference the real GNV directory tree.
+
+Then a local copy of the GNU/GNV$GNU logical names can be set up as a search
+list such as NEW_GNU:,OLD_GNU:
+
+The directory NEW_GNU:[usr] should be created.  The make install phase should
+create all the other directories.
+
+The make install process may abort if curl is already because it can not
+uninstall the older version of curl because it does not have permission.
+
+The file stage_curl_install.com is used set up a new_gnu: directory tree
+for testing.  The PCSI kitting procedure uses these files as input.
+
+These files do not create the directories in the VMS_ROOT and LCL_ROOT
+directory trees.  You can create them with commands similar to:
+
+  $ create/dir lcl_root:[curl]/prot=w:re
+  $ copy src_root:[curl...]*.dir -
+    lcl_root:[curl...]/prot=(o:rwed,w:re)
+  $ create/dir vms_root:[curl]/prot=w:re
+  $ copy src_root:[curl...]*.dir -
+    vms_root:[curl...]/prot=(o:rwed,w:re)
+
+One of the ways with to protect the source from being modified is to have
+the directories under src_root: owned by a user or resource where the build
+username only has read access to it.
+
+
+Note to builders:
+
+GNV currently has a bug where configure scripts take a long time to run.
+Some of the configure steps take a while to complete, and on a 600 Mhz
+DS10 with IDE disks, taking an hour to run the CURL configure is normal.
+
+The following messages can be ignored and may get fixed in a future version
+of GNV.  The GNV$*.OPT files are used to find the libraries as many have
+different names on VMS than on Unix.  The Bash environment variable
+GNV_CC_QUALIFIERS can override all other settings for the C Compiler.
+
+? cc: No support for switch -warnprotos
+? cc: Unrecognized file toomanyargs
+? cc: Warning: library "ssl" not found
+? cc: Warning: library "crypto" not found
+? cc: Warning: library "gssapi" not found
+? cc: Warning: library "z" not found
+u unimplemented switch - ignored
+
+
+With these search lists set up and the properly, curl can be built by
+setting your default to PRJ_ROOT:[curl.packages.vms] and then issuing
+either the command:
+
+  $ @pcsi_product_gnv_curl.com
+
+or
+
+  $ @build_gnv_curl.com.
+
+The GNV configure procedure takes considerably longer than the DCL build
+procedure takes.  It is of use for testing the GNV build environment, and
+may not have been kept up to date.
+
+The pcsi_product_gnv_curl.com needs the following logical names which
+are described in the section below:
+
+  gnv_pcsi_producer
+  gnv_pcsi_producer_full_name
+  stage_root
+  vms_root1 (Optional if vms_root is on a NFS volume)
+  src_root1 (Optional if src_root is on a NFS volume)
+
+The pcsi_product_gnv_curl.com is described in more detail below.  It does
+the following steps.  The build steps are only done if they are needed to
+allow using either DCL or GNV based building procedures.
+
+  $ @build_vms list
+
+  $ @gnv_link_curl.com
+
+  $ @build_gnv_curl_release_notes.com
+
+  $ @backup_gnv_curl_src.com
+
+  $ @build_gnv_curl_pcsi_desc.com
+
+  $ @build_gnv_curl_pcsi_text.com
+
+  $ @stage_curl_install remove
+  $ @stage_curl_install
+
+  Then builds the kit.
+
+The build_gnv_curl.com command procedure does the following:
+
+  $ @setup_gnv_curl_build.com
+
+  $ bash gnv_curl_configure.sh
+
+  $ @clean_gnv_curl.com
+
+  $ bash make_gnv_curl_install.sh
+
+  $ @gnv_link_curl.com
+
+  $ @stage_curl_install.com
+
+  $ purge new_gnu:[*...]/log
+
+To clean up after a GNV based build to start over, the following commands are
+used:
+
+   $ bash
+   bash$ cd ../..
+   bash$ make clean
+   bash$ exit
+
+Then run the @clean_gnv_curl.com.  Use the parameter "realclean" if you are
+going to run the setup_gnv_curl_build.com and configure script again.
+
+   $ @clean_gnv_curl.com realclean
+
+If new public symbols have been added, adjust the file gnv_libcurl_symbols.opt
+to have the new symbols.  If the symbols are longer than 32 characters,
+then they will need to have the original be exact case CRC shortened and
+an alias in upper case with CRC shortened, in addition to having an exact
+case truncated alias and an uppercase truncated alias.
+
+The *.EXE files are not moved to the new_gnu: directory.
+
+After you are satisfied with the results of your build, you can move the
+files from new_gnu: to old_gnu: at your convenience.
+
+Building a PCSI kit for an architecture takes the following steps after
+making sure that you have a working build environment.
+
+Note that it requires manually creating two logical names as described
+below.  It is intentional that they be manually set.  This is for
+branding the PCSI kit based on who is making the kit.
+
+   1. Make sure that you have a staging directory that can be referenced
+      by the path STAGE_ROOT:[KIT]
+
+   2. Edit the file curl_release_note_start.txt or other text files to
+      reflect any changes.
+
+   3. Define the logical name GNV_PCSI_PRODUCER to indicate who is making
+      the distribution.  For making updates to an existing open source
+      kit you may need to keep the producer the same.
+
+   4. Define the logical name GNV_PCSI_PRODUCER_FULL_NAME to be your full
+      name or full name of your company.
+
+   5. If you are producing an update kit, then update the file
+      vms_eco_level.h by changing the value for the VMS_ECO_LEVEL macro.
+      This file is currently only used in building the PCSI kit.
+
+   6. Edit the file PCSI_GNV_CURL_FILE_LIST.TXT if there are new files added
+      to the kit.  These files should all be ODS-2 legal filenames and
+      directories.
+
+      A limitation of the PCSI kitting procedure is that when selecting files,
+      it tends to ignore the directory structure and assumes that all files
+      with the same name are the same file, so every file placed in the kit
+      must have a unique name.  Then a procedure needs to be added to the kit
+      to create an alias link on install and remove the link on remove.
+
+      Since at this time curl does not need this alias procedure, the steps
+      to automatically build it are not included here.
+
+      While newer versions of PCSI can support ODS-5 filenames, not all versions
+      of PCSI on systems that have ODS-5 filenames do.  So as a post install
+      step, the PCSI kit built by these steps does a rename to the correct
+      case as a post install step.
+
+   7. Edit the build_curl_pcsi_desc.com and build_curl_pcsi_text.com if you
+      have changed the version of ZLIB that curl is built against.
+
+   8. Prepare to backup the files for building the kit.
+
+      Note that if src_root: or vms_root: are NFS mounted disks, the
+      step of backing up the source files will probably hang or fail.
+
+      You need to copy the source files to VMS mounted disks and create
+      logical names SRC_ROOT1 and VMS_ROOT1 to work around this to to
+      reference local disks.  Make sure src_root1:[000000] and
+      vms_root1:[000000] exist and can be written to.
+
+      The command procedure compare_curl_source can be used to check
+      those directories and keep them up to date.
+
+         @compare_curl_source.com SRCBCK UPDATE
+
+         This compares the reference project source with the backup
+         staging directory for it and updates with any changes.
+
+         @compare_curl_source.com VMSBCK UPDATE
+
+         This compares the VMS specific source with the backup
+         staging directory for it and updates with any changes.
+
+         Leave off "UPDATE" to just check without doing any changes.
+
+      If you are not using NFS mounted disks and do not want to have a
+      separate directory for staging the sources for backup make sure
+      that src_root1: and vms_root1: do not exist.
+
+   9. Build the PCSI kit with @pcsi_product_gnv_curl.com
+
+       The following message is normal:
+          %PCSI-I-CANNOTVAL, cannot validate
+            EAGLE$DQA0:[stage_root.][kit]VMSPORTS-AXPVMS-CURL-V0731-0-1.PCSI;1
+          -PCSI-I-NOTSIGNED, product kit is not signed and therefore has
+          no manifest file
+
+       This will result in an uncompressed kit for the target platform.
+       On Alpha and Integrity, the pcsi_product_gnv_curl.com can be used with
+       the "COMPRESSED" parameter to build both a compressed and uncompressed
+       kits.
+
+Good Luck.

+From file: CURL_RELEASE_NOTE_START.TXT
+
+Note: These kits are produced by a hobbyist and are providing any support
+or any commitment to supply bug fixes or future releases.  This code is
+as-is with no warrantees.
+
+The testing of this build of curl was minimal and involved building some of
+the sample and test programs, accessing a public HTTPS: website, doing a
+form post of some VMS test files, and FTP upload of some text files.
+
+Due to the way that PCSI identifies packages, if you install a package from
+one producer and then want to upgrade it from another producer, you will
+probably need to uninstall the previous package first.
+
+OpenVMS specific building and kitting instructions are after the standard
+curl readme file.
+
+This product may be available for your platform in a PCSI kit.  The source kit
+contains files for building CURL using GNV or with a DCL procedure.
+
+The GNV based build creates a libcurl share imaged which is supplied in the
+PCSI kit.
+
+This version of CURL will return VMS compatible status codes when run from
+DCL and Unix compatible exit codes and messages when run with the SHELL
+environment variable set.
+
+This port of Curl uses the OpenSSL, Ldap, and Kerberos V5 that are bundled
+with OpenVMS or supplied as updates by HP.  Ldap and Kerberos are not available
+on the VAX platform.  See section below for a special note about HP OpenSSL
+on Alpha and IA64.
+
+The supplied CURL_STARTUP.COM procedure that is installed in
+[VMS$COMMON.SYS$STARTUP] can be put in your VMS startup procedure to install
+the GNV$LIBCURL shared image and create logical names GNV$LIBCURL to reference
+it.  It will create the GNV$CURL_INCLUDE logical name for build procedures
+to access the header files.
+
+Normally to use curl from DCL, just create a foreign command as:
+   curl :== $gnv$gnu:[usr.bin]gnv$curl.exe
+
+If you need to work around having the older HP SSL kit installed, then
+for DCL create this command procedure:
+
+ $ create/dir gnv$gnu:[vms_bin]/prot=w:re
+ $ create gnv$gnu:[vms_bin]curl.com
+ $ curl := $gnv$gnu:[usr.bin]gnv$curl.exe
+ $ define/user ssl$libcrypto_shr32 gnv$curl_ssl_libcryptoshr32
+ $ curl "''p1'" "''p2'" "''p3'" "''p4'" "''p5'" "''p6'" "''p7'" "''p8'"
+ ^Z
+
+Then you can use: curl :== @gnv$gnu:[vms_bin]curl.com to run curl.
+
+For the HP SSL work around to work for GNV do the following:
+ $ create/dir gnv$gnu:[usr.local.bin]/prot=w:re
+ $ create gnv$gnu:[usr.local.bin]curl.
+ #! /bin/sh
+ dcl @gnv\$gnu:[vms_bin]curl.com $*
+ ^Z
+
+Similar work arounds will be needed for any program linked with GNV$LIBCURL
+until the HP OpenSSL is upgraded to the current 1.4 version or later.
+
+If you are installing a "daily" build instead of a release build of Curl, some
+things have been changed so that it can be installed at the same time as
+a production build with out conflicts.
+
+   The CURL_DAILY_STARTUP.COM will be supplied instead of CURL_STARTUP.COM.
+   This file is actually not used with the daily package and is provided as
+   a preview of what the next CURL_STARTUP.COM will be for the next release.
+   Do not run it.
+
+   The files that are normally installed in [VMS$COMMON.GNV.usr], for the
+   daily build are installed in [VMS$COMMON.GNV.beta] directory.
+
+   To use the daily GNV$LIBCURL image, you will need to define the logical
+   name GNV$LIBCURL to the image.

+$! File: GENERATE_CONFIG_H_CURL.COM
+$!
+$! $Id$
+$!
+$! Curl like most open source products uses a variant of a config.h file.
+$! Depending on the curl version, this could be config.h or curl_config.h.
+$!
+$! For GNV based builds, the configure script is run and that produces
+$! a [curl_]config.h file.  Configure scripts on VMS generally do not
+$! know how to do everything, so there is also a [-.lib]config-vms.h file
+$! that has VMS specific code that compensates for bugs in some of the
+$! VMS shared images.
+$!
+$! This generates a [curl_]config.h file and also a config_vms.h file,
+$! which is used to supplement that file.  Note that the config_vms.h file
+$! and the [.lib]config-vms.h file do two different tasks and that the
+$! filenames are slightly different.

+! File GNV$LIBCURL_SYMBOLS.OPT
+!
+! $Id$
+!
+! This file must be manually maintained to allow upward compatibility
+! The SYMBOL_VECTORs are set up so that applications can be compiled
+! with either case sensitive symbol names or the default of uppercase.
+! This is because many of the Open Source applications that would call
+! the LIBCURL library need to be built with case sensitive names.
+!
+! Automatic generation is currently not practical because the order of
+! the entries are important for upward compatibility.
+!
+! The GSMATCH is manually set to the major version of 1, with the minor
+! version being the next two sections multiplied by a power of 10 to
+! become the minor version.
+! So LIBCURL 7.18.1 becomes 1,718010.
+! And a future LIBCURL of 7.18.2 would be 1,718020 if new routines were added.
+!
+! This leaves some spare digits for minor patches.
+!
+! Note that the GSMATCH does not need to have any real relationship to the
+! actual package version number.
+!
+! New SYMBOL_VECTORs must be added to the end of this list, and added
+! in pairs for both exact and with an uppercase alias.
+! If the public symbol is more than 31 characters long, then a special
+! shortened symbol will be exported, and three aliases should be created,
+! The aliases will be the special shortened uppercase alias, and both
+! upper and lowercase versions of a truncated name (preferred) or a
+! modified manually shortened name if a truncated name will not be
+! unique.
+!
+! Routines can not be removed, the functionality must be maintained.
+! If a new routine is supplied where the arguments are incompatible with
+! the older version, both versions are needed to be maintained.
+! The old version can be given a different name, but must be in the same
+! SYMBOL_VECTOR positions in this file.
+!
+! Changing the number of parameters for an existing routine does not require
+! maintaining multiple versions as long as the routine can be called with
+! the old number of parameters.

+This package is built on with the OpenSSL version listed below and requires
+the shared images from the HP OpenSSL product that is kitted with that
+version or a compatible later version.
+
+For Alpha and IA64 platforms, see the url below to register to get the
+download URL.  The kit will be HP 1.4-467 or later.
+  https://h41379.www4.hpe.com/openvms/products/ssl/ssl.html
+
+For VAX, use the same registration, but remove the kit name from any of the
+download URLs provided and put in CPQ-VAXVMS-SSL-V0101-B-1.PCSI-DCX_VAXEXE
+
+If your system can not be upgraded to a compatible version of OpenSSL, then
+you can extract the two shared images from the kit and place them in the
+[vms$common.gnv.lib]directory of the volume that you are installing GNV and
+or GNV compatible components like Curl.
+
+If GNV is installed, you must run the GNV startup procedure before these steps
+and before installing Curl.
+
+
+  1.  make sure that [vms$common.gnv.lib] exists by using the following
+      commands.  We want the directory to be in lowercase except on VAX.
+
+    $SET PROCESS/PARSE=extend !If not VAX.
+    $CREATE/DIR device:[vms$common.gnv.lib]/prot=w:re
+
+  2. Extract the ssl$crypto_shr32.exe and ssl$libssl_shr32.exe images.
+
+    $PRODUCT EXTRACT FILE -
+      /select=(ssl$libcrypto_shr32.exe,ssl$libssl_shr32.exe)-
+      /source=device:[dir] -
+      /options=noconfirm -
+      /destination=device:[vms$common.gnv.lib] SSL
+
+The [vms$common.sys$startup}curl_startup.com procedure will then configure
+libcurl to use these shared images instead of the system ones.
+
+When you upgrade SSL on VMS to the newer version of HP SSL, then these copies
+should be deleted.

+                        shared image has been made.
+
+readme.                 This file.
+
+report_openssl_version.c
+                        Program to check that the openssl version is new
+                        enough for building a shared libcurl image.
+
+setup_gnv_curl_build.com
+                        This procedure sets up symbols and logical names
+                        for a GNV build environment and also copies some
+                        helper files.
+
+stage_curl_install.com  This procedure sets up new_gnu: directory tree to
+                        for testing the install and building the PCSI kit.
+                        It takes a "remove" option to remove all the staged
+                        files.
+
+vms_eco_level.h         This sets the ECO level for the PCSI kit name.
+
+
+How to Build:
+
+The GNV based build and the DCL based build procedures are not compatible
+and you must make sure that none of the build files are present before
+running a different type of build.  Use the "REALCLEAN" option for
+BUILD_VMS.COM and the "REALCLEAN" option for clean_gnv_curl.com.
+
+The (brute-force) DCL based builder is [.packages.vms]build_vms.com.
+Comments in this procedure describe various optional parameters which
+enable or disable optional program features, or which control the build
+in other ways.  Product files (.EXE, .H, .LIS, .MAP, .OBJ, .OLB, ...)
+should be produced in an architecture-specific subdirectory under this
+directory ([.ALPHA], [.IA64], [.VAX]).
+
+The file curl_gnv_build_steps.txt contains information on building using
+the GNV tool kit, building a shared libcurl, and producing a PCSI kit for
+distribution.  The curl_gnv_build_steps.text is included in the release
+notes file of the PCSI kit.
+
+The building with 64 bit pointers does not currently work.
+
+The build procedure will detect if HP OpenSSL, LDAP, and Kerberos are
+installed and default to building with them.
+
+The build procedure will also detect if a compatible ZLIB shared image
+is installed from a PCSI kit and default to using it.
+
+   Example build commands:
+
+      @ [.packages.vms]build_vms.com CLEAN
+      @ [.packages.vms]build_vms.com LARGE LDAP
+      submit /noprint [.packages.vms]build_vms.com /param = (LARGE, LDAP)
+
+The build_vms.com procedure does not build the shared image file or the PCSI
+kit.  If you have built a curl with ZLIB and HPSSL support as well as if
+LDAP and Kerberos installed, you can use the GNV_LINK_CURL.COM file.
+
+The GNV_LINK_CURL.COM contains information on how to link and run with a newer
+version of HP SSL than what may be install on an Alpha or IA64 based system.
+
+To build the PCSI kit, follow the instructions in the file
+curl_gnv_build_steps.txt.
+
+Other Notes:
+
+This release fixes known bugs #22, and #57 in the [curl.docs]known_bugs.
+file.
+
+The libcurl formdata.c module and Curl tools post form now have some
+understanding of VMS file types.  Files will be posted in STREAM_LF format.
+
+The Curl tool now has some understanding of VMS file types and will upload the
+files in STREAM_LF format.
+
+When CURL is uploading a VARIABLE format VMS file, it is less efficient as in
+order to get the file size, it will first read the entire file once, and then
+read the file again for the actual upload.
+
+The Curl tool will now always download files into STREAM_LF format.  Even if a
+file by that name with a different format already exists.  This is needed to
+allow interrupted downloads to be continued.
+
+
+The libcurl file module still does not understand VMS file types and requires
+the input files to be in STREAM_LF to work property.
+
+The test suites are not supported as of 7.11.0.
+
+The curlmsg.sdl and curlmsg.h files are generated from curlmsg.msg.
+This is not done automatically, since the .MSG file is a hand edit
+of the relevant stuff from the curl.h file.  If you want to do this
+yourself you'll need the SDL package from the freeware collection.

+This document describes how to compile, build and install curl and libcurl
+from sources using mk. To build it, you will require to install latest
+9legacy patches into Plan 9. Also Plan 9 still have no configuration option so
+both zlib and libopenssl are required too.

+The zlib that is available on Plan 9 can be downloaded from:

+  https://github.com/madler/zlib/pull/398
+
+LibreSSL Portable can be downloaded from:
+
+  https://github.com/libressl-portable/portable/pull/510
+
+Instruction
+===========
+First, you should construct namespace as like described below:
+
+% bind -ac ../lib lib
+% bind -ac ../src src
+% bind -ac ../include include
+% bind -ac .. .
+
+Then you will see as shown below (excerpt):
+
+  curl.git/
+   |_plan9
+   | |_BUILD.PLAN9.txt
+   | |_CHANGES
+   | |_CMake
+   | |  :
+   | |_mkfile
+   | |_mkfile.proto
+   | |_include
+   | | |_Makefile.am
+   | | |  :
+   | | |_mkfile
+   | |_lib
+   | | |_CMakeLists.txt
+   | | |  :
+   | | |_mkfile
+   | | |_mkfile.inc
+   | |_src
+   | | |_CMakeLists.txt
+   | | |  :
+   | | |_mkfile
+   | | |_mkfile.inc
+   |_lib
+   |_src
+
+After constructing namespace, you can run mk on plan9 directory.
+
+% mk
+% mk install

+# ==== How to use this script ====
+#
+# 1. Get recent commits added to RELEASE-NOTES:
+#
+# $ ./scripts/release-notes.pl
+#
+# 2. Edit RELEASE-NOTES and remove all entries that don't belong.  Unused
+# references below will be cleaned up in the next step. Make sure to move
+# "changes" up to the changes section. All entries will by default be listed
+# under bug-fixes as this script can't know where to put them.
+#
+# 3. Run the cleanup script and let it sort the entries and remove unused
+# references from lines you removed in step (2):
+#
+# $ ./script/release-notes.pl cleanup
+#
+# 4. Reload RELEASE-NOTES and verify that things look okay. The cleanup
+# procedure can and should be re-run when lines are removed or rephrased.
+#
+# 5. Run ./scripts/contributors.sh and update the contributor list of names
+# The list can also be extended or edited manually.
+#
+# 6. Run ./scripts/delta and update the contributor count at the top, and
+# double-check/update the other counters.
+#
+# 7. Commit the file using "RELEASE-NOTES: synced" as commit message.

+MACOS (not MACOS X)
===================
This is the first attempt at porting curl to MacOS.
http, ftp, dict and telnet seems to work fine, other protocols and advanced 
features have not been all tested.

This port is heavily based on the GUSI library from Matthias Neeracher.
GUSI (Grand Unified Socket Interface) is a POSIX/Pthreads/Sockets library 
bringing some of the comforts of UNIX 98 to traditional MacOS.
The latest GUSI release can be downloaded from sourceforge 
at <https://sourceforge.net/projects/gusi/>

I have also written a few functions to help port Unix applications to MacOS.
These functions are part of the GUSI Extra library that can be downloaded at
<http://perso.wanadoo.fr/ela/resources.html#gusiextra>

OpenSSL support is still experimental but I hope to deliver a version 
including SSL soon.

curl for MacOS requires using the CodeWarrior compiler from Metrowerks.

First download GUSI, GUSI Extra and curl. Access paths have been setup so that
GUSI, GUSI Extra and curl directories should have the same parent directory.

Follow the instructions in GUSI Extra "readme.txt" mainly the ones related to
SIOUX and GUSI patches. If you do not apply these patches curl will not behave 
correctly.

In the 'curl/src/macos' directory, decode "curl.mcp.xml.sit.hqx" (This is a 
stuffit binhexed file)
From the CodeWarrior IDE, import 'curl/src/macos/curl.xml', adjust the access 
paths if required. Then you should be able to build:
- the libcurl libraries for PPC and 68K.
- the curl application (also available for PPC and 68K) which is the command
  line version of curl.

If the file "tool_hugehelp.c" is missing rename "curl/src/tool_hugehelp.c.cvs"
to "tool_hugehelp.c" and make sure its file type is 'TEXT'

+# Building curl with Visual C++
+
+ This document describes how to compile, build and install curl and libcurl
+ from sources using the Visual C++ build tool. To build with VC++, you will of
+ course have to first install VC++. The minimum required version of VC is 6
+ (part of Visual Studio 6). However using a more recent version is strongly
+ recommended.
+
+ VC++ is also part of the Windows Platform SDK. You do not have to install the
+ full Visual Studio or Visual C++ if all you want is to build curl.
+
+ The latest Platform SDK can be downloaded freely from [Windows SDK and
+ emulator
+ archive](https://developer.microsoft.com/en-us/windows/downloads/sdk-archive)
+
+## Prerequisites
+
+ If you wish to support zlib, openssl, c-ares, ssh2, you will have to download
+ them separately and copy them to the deps directory as shown below:
+
+    somedirectory\
+     |_curl-src
+     | |_winbuild
+     |
+     |_deps
+       |_ lib
+       |_ include
+       |_ bin
+
+ It is also possible to create the deps directory in some other random places
+ and tell the Makefile its location using the WITH_DEVEL option.
+
+## Building straight from git
+
+ When you check out code git and build it, as opposed from a released source
+ code archive, you need to first run the `buildconf.bat` batch file (present
+ in the source code root directory) to set things up.
+
+## Open a command prompt
+
+Open a Visual Studio Command prompt:
+
+ Using the **'Developer Command Prompt for VS [version]'** menu entry: where
+ [version} is the Visual Studio version. The developer prompt at default uses
+ the x86 mode. It is required to call `Vcvarsall.bat` to setup the prompt for
+ the machine type you want. This type of command prompt may not exist in all
+ Visual Studio versions.
+
+ See also: [Developer Command Prompt for Visual
+ Studio](https://docs.microsoft.com/en-us/dotnet/framework/tools/developer-command-prompt-for-vs)
+ and [How to: Enable a 64-Bit, x64 hosted MSVC toolset on the command
+ line](https://docs.microsoft.com/en-us/cpp/build/how-to-enable-a-64-bit-visual-cpp-toolset-on-the-command-line)
+
+ Using the **'VS [version] [platform] [type] Command Prompt'** menu entry:
+ where [version] is the Visual Studio version, [platform] is e.g. x64 and
+ [type] Native of Cross platform build.  This type of command prompt may not
+ exist in all Visual Studio versions.
+
+ See also: [Set the Path and Environment Variables for Command-Line Builds](https://msdn.microsoft.com/en-us/library/f2ccy3wt.aspx)
+
+## Build in the console
+
+ Once you are in the console, go to the winbuild directory in the Curl
+ sources:
+
+    cd curl-src\winbuild
+
+ Then you can call `nmake /f Makefile.vc` with the desired options (see
+ below). The builds will be in the top src directory, `builds\` directory, in
+ a directory named using the options given to the nmake call.
+
+    nmake /f Makefile.vc mode=<static or dll> <options>
+
+where `<options>` is one or many of:
+
+ - `VC=<6,7,8,9,10,11,12,14,15>` - VC version
+ - `WITH_DEVEL=<path>`           - Paths for the development files (SSL, zlib, etc.)
+                                   Defaults to sibbling directory deps: ../deps
+                                   Libraries can be fetched at https://windows.php.net/downloads/php-sdk/deps/
+                                   Uncompress them into the deps folder.
+ - `WITH_SSL=<dll/static>`       - Enable OpenSSL support, DLL or static
+ - `WITH_NGHTTP2=<dll/static>`   - Enable HTTP/2 support, DLL or static
+ - `WITH_MBEDTLS=<dll/static>`   - Enable mbedTLS support, DLL or static
+ - `WITH_CARES=<dll/static>`     - Enable c-ares support, DLL or static
+ - `WITH_ZLIB=<dll/static>`      - Enable zlib support, DLL or static
+ - `WITH_SSH2=<dll/static>`      - Enable libSSH2 support, DLL or static
+ - `WITH_PREFIX=<dir>`           - Where to install the build
+ - `ENABLE_SSPI=<yes/no>`        - Enable SSPI support, defaults to yes
+ - `ENABLE_IPV6=<yes/no>`        - Enable IPv6, defaults to yes
+ - `ENABLE_IDN=<yes or no>`      - Enable use of Windows IDN APIs, defaults to yes
+                                   Requires Windows Vista or later
+ - `ENABLE_SCHANNEL=<yes/no>`    - Enable native Windows SSL support, defaults
+                                   to yes if SSPI and no other SSL library
+ - `ENABLE_OPENSSL_AUTO_LOAD_CONFIG=<yes/no>`
+                                 - Enable loading OpenSSL configuration
+                                   automatically, defaults to yes
+ - `ENABLE_UNICODE=<yes/no>`     - Enable UNICODE support, defaults to no
+ - `GEN_PDB=<yes/no>`            - Generate Program Database (debug symbols for release build)
+ - `DEBUG=<yes/no>`              - Debug builds
+ - `MACHINE=<x86/x64>`           - Target architecture (default is x86)
+ - `CARES_PATH=<path>`           - Custom path for c-ares
+ - `MBEDTLS_PATH=<path>`         - Custom path for mbedTLS
+ - `NGHTTP2_PATH=<path>`         - Custom path for nghttp2
+ - `SSH2_PATH=<path>`            - Custom path for libSSH2
+ - `SSL_PATH=<path>`             - Custom path for OpenSSL
+ - `ZLIB_PATH=<path>`            - Custom path for zlib
+
+## Static linking of Microsoft's C RunTime (CRT):
+
+ If you are using mode=static nmake will create and link to the static build
+ of libcurl but *not* the static CRT. If you must you can force nmake to link
+ in the static CRT by passing RTLIBCFG=static. Typically you shouldn't use
+ that option, and nmake will default to the DLL CRT. RTLIBCFG is rarely used
+ and therefore rarely tested. When passing RTLIBCFG for a configuration that
+ was already built but not with that option, or if the option was specified
+ differently, you must destroy the build directory containing the
+ configuration so that nmake can build it from scratch.
+
+## Building your own application with a static libcurl
+
+ When building an application that uses the static libcurl library on Windows,
+ you must define CURL_STATICLIB. Otherwise the linker will look for dynamic
+ import symbols.
+
+## Legacy Windows and SSL
+
+ When you build curl using the build files in this directory the default SSL
+ backend will be Schannel (Windows SSPI), the native SSL library that comes
+ with the Windows OS. Schannel in Windows <= XP is not able to connect to
+ servers that no longer support the legacy handshakes and algorithms used by
+ those versions. If you will be using curl in one of those earlier versions of
+ Windows you should choose another SSL backend like OpenSSL.

+
+# Why?
+Just for the novelty of using a C++ library for Discord. I would also love for this thing to work on many things like consoles and maybe some microcontrollers.
+
+# Example
+```cpp
+#include "sleepy_discord/sleepy_discord.h"
+
+class MyClientClass : public SleepyDiscord::DiscordClient {
+public:
+	using SleepyDiscord::DiscordClient::DiscordClient;
+	void onMessage(SleepyDiscord::Message message) override {
+		if (message.startsWith("whcg hello"))
+			sendMessage(message.channelID, "Hello " + message.author.username);
+	}
+};
+
+int main() {
+	myClientClass client("token", SleepyDiscord::USER_CONTROLED_THREADS);
+	client.run();
+}
+```
+Input: Message received
+```
+whcg hello
+```
+Possible Output: Message sent
+```
+Hello Sleepy Flower Girl
+```

+# Will Updating the library break my bot?
+
+Yes, and for now I don't plan on making 0.0 versions backwards compatible with 1.0 versions or later.
+
+# Requirements
+Sleepy Discord doesn't require you to use any libraries, so that you can use any library you wish or your own code. However, Sleepy Discord provides native support for a few libraries and it is recommend you use those instead of writing your own.
+
+* [OpenSSL](https://www.openssl.org/)
+* [cpr](https://github.com/whoshuu/cpr)
+* [Websocket++](https://github.com/zaphoyd/websocketpp)
+or
+[uWebSockets](https://github.com/uWebSockets/uWebSockets)
+
+# Develop Branch
+For the cutting edge of Sleepy Discord, check out the develop branch. Please use the develop branch with caution because it may not even be able to compile or it is 100% not tested at all. Other then that, the branch is used for code that may not work. Also check to see if it's not behind the master branch, unless you want to use an older version of Sleepy Discord.

+# MODULE:   DownloadProject
+#
+# PROVIDES:
+#   download_project( PROJ projectName
+#                    [PREFIX prefixDir]
+#                    [DOWNLOAD_DIR downloadDir]
+#                    [SOURCE_DIR srcDir]
+#                    [BINARY_DIR binDir]
+#                    [QUIET]
+#                    ...
+#   )
+#
+#       Provides the ability to download and unpack a tarball, zip file, git repository,
+#       etc. at configure time (i.e. when the cmake command is run). How the downloaded
+#       and unpacked contents are used is up to the caller, but the motivating case is
+#       to download source code which can then be included directly in the build with
+#       add_subdirectory() after the call to download_project(). Source and build
+#       directories are set up with this in mind.
+#
+#       The PROJ argument is required. The projectName value will be used to construct
+#       the following variables upon exit (obviously replace projectName with its actual
+#       value):
+#
+#           projectName_SOURCE_DIR
+#           projectName_BINARY_DIR
+#
+#       The SOURCE_DIR and BINARY_DIR arguments are optional and would not typically
+#       need to be provided. They can be specified if you want the downloaded source
+#       and build directories to be located in a specific place. The contents of
+#       projectName_SOURCE_DIR and projectName_BINARY_DIR will be populated with the
+#       locations used whether you provide SOURCE_DIR/BINARY_DIR or not.
+#
+#       The DOWNLOAD_DIR argument does not normally need to be set. It controls the
+#       location of the temporary CMake build used to perform the download.
+#
+#       The PREFIX argument can be provided to change the base location of the default
+#       values of DOWNLOAD_DIR, SOURCE_DIR and BINARY_DIR. If all of those three arguments
+#       are provided, then PREFIX will have no effect. The default value for PREFIX is
+#       CMAKE_BINARY_DIR.
+#
+#       The QUIET option can be given if you do not want to show the output associated
+#       with downloading the specified project.
+#
+#       In addition to the above, any other options are passed through unmodified to
+#       ExternalProject_Add() to perform the actual download, patch and update steps.
+#       The following ExternalProject_Add() options are explicitly prohibited (they
+#       are reserved for use by the download_project() command):
+#
+#           CONFIGURE_COMMAND
+#           BUILD_COMMAND
+#           INSTALL_COMMAND
+#           TEST_COMMAND
+#
+#       Only those ExternalProject_Add() arguments which relate to downloading, patching
+#       and updating of the project sources are intended to be used. Also note that at
+#       least one set of download-related arguments are required.
+#
+#       If using CMake 3.2 or later, the UPDATE_DISCONNECTED option can be used to
+#       prevent a check at the remote end for changes every time CMake is run
+#       after the first successful download. See the documentation of the ExternalProject
+#       module for more information. It is likely you will want to use this option if it
+#       is available to you. Note, however, that the ExternalProject implementation contains
+#       bugs which result in incorrect handling of the UPDATE_DISCONNECTED option when
+#       using the URL download method or when specifying a SOURCE_DIR with no download
+#       method. Fixes for these have been created, the last of which is scheduled for
+#       inclusion in CMake 3.8.0. Details can be found here:
+#
+#           https://gitlab.kitware.com/cmake/cmake/commit/bdca68388bd57f8302d3c1d83d691034b7ffa70c
+#           https://gitlab.kitware.com/cmake/cmake/issues/16428
+#
+#       If you experience build errors related to the update step, consider avoiding
+#       the use of UPDATE_DISCONNECTED.
+#
+# EXAMPLE USAGE:

+// GenericPointer
+
+//! Represents a JSON Pointer. Use Pointer for UTF8 encoding and default allocator.
+/*!
+    This class implements RFC 6901 "JavaScript Object Notation (JSON) Pointer" 
+    (https://tools.ietf.org/html/rfc6901).
+
+    A JSON pointer is for identifying a specific value in a JSON document
+    (GenericDocument). It can simplify coding of DOM tree manipulation, because it
+    can access multiple-level depth of DOM tree with single API call.
+
+    After it parses a string representation (e.g. "/foo/0" or URI fragment 
+    representation (e.g. "#/foo/0") into its internal representation (tokens),
+    it can be used to resolve a specific value in multiple documents, or sub-tree 
+    of documents.
+
+    Contrary to GenericValue, Pointer can be copy constructed and copy assigned.
+    Apart from assignment, a Pointer cannot be modified after construction.
+
+    Although Pointer is very convenient, please aware that constructing Pointer
+    involves parsing and dynamic memory allocation. A special constructor with user-
+    supplied tokens eliminates these.
+
+    GenericPointer depends on GenericDocument and GenericValue.
+    
+    \tparam ValueType The value type of the DOM tree. E.g. GenericValue<UTF8<> >
+    \tparam Allocator The allocator type for allocating memory for internal representation.
+    
+    \note GenericPointer uses same encoding of ValueType.
+    However, Allocator of GenericPointer is independent of Allocator of Value.
+*/
+template <typename ValueType, typename Allocator = CrtAllocator>
+class GenericPointer {
+public:
+    typedef typename ValueType::EncodingType EncodingType;  //!< Encoding type from Value
+    typedef typename ValueType::Ch Ch;                      //!< Character type from Value
+
+    //! A token is the basic units of internal representation.
+    /*!
+        A JSON pointer string representation "/foo/123" is parsed to two tokens: 
+        "foo" and 123. 123 will be represented in both numeric form and string form.
+        They are resolved according to the actual value type (object or array).
+
+        For token that are not numbers, or the numeric value is out of bound
+        (greater than limits of SizeType), they are only treated as string form
+        (i.e. the token's index will be equal to kPointerInvalidIndex).
+

+Why aren't the message_create events bundled with an isprivate identifier?
+
+Danny - Today at 10:29 PM
+1. sleepy_c++_discord_library.h is an awful library name, consider using something a bit more sane like sleepy_discord.hpp or something.
+2. C++ style guide is snake_case not ThisCase or thisCase.
+3. SleepyDiscord::init is a global function that is a C-ism. C++ we tend to use RAII.
+4. Your use of new myEventClass has no notion of ownership.
+5. Your parameter jsonMessage has no notion of ownership.
+6. Forcing your users to do the heartbeat themselves is poor design.
+7. Sleep is not a standard function. std::this_thread::sleep_for(std::chrono::seconds(1)) is though.
+8. heartbeat is a global function again which makes me wonder how your design is.
+9. Casting to std::string like (std::string)message.author.username is most definitely the wrong thing to do.
+
+based on your code I don't even think you know what modern C++ is
+look up C++11/14/17
+
+meh
+ownership woes still
+and then there's the responsibility of creating the message
+also I don't like your message API
+std::string already exists.
+e.g. message.content.find("whcg hello") == 0 works too
+and you could then use message.content with whatever accepts an std::string
+for all I know message.content already exists.
+
+it's pretty meh
+I don't want some parsed JSON object
+if you're gonna use boost.asio use it all the way through

+That's a pretty bad way of passing data. I guess if it's written in C it makes sense but you should have written a thin wrapper in C++ for it
+
+I see, you are manually constructing JSON payload too
+Sleepy Flower Girl - Today at 2:28 AM
+yea
+I don't see that as problem yet
+qwename - Today at 2:29 AM
+Well, it's error-prone, and you might not know the intricacies of JSON enough
+TiltMeSenpai - Today at 2:29 AM
+there is a json lib for cpp floating around
+you want that?
+Sleepy Flower Girl - Today at 2:29 AM
+I don't need a json lib
+qwename - Today at 2:30 AM
+The least you can do is pack it into a helper function
+Sleepy Flower Girl - Today at 2:30 AM
+I understand it enugh that I don't need a lib for that
+qwename - Today at 2:31 AM
+I pass a dictionary around until I actually need to send the data, then I call a library function to return a JSON payload
+The point isn't whether you understand it or not(edited)
+TiltMeSenpai - Today at 2:31 AM
+ok that's not horrible actually
+qwename - Today at 2:31 AM
+Right now you have to specify all the curly brackets and commas and whatnot(edited)
+NEW MESSAGES
+qwename - Today at 2:32 AM
+Which takes away time and effort from what you are actually accomplishing
+So I suggest the minimum of putting that in a helper method.
+I think the map class is an associative array that can do what you need
+From <map>
+
+zey - Today at 12:24 AM
+i mention someone if
+- they'll otherwise miss it
+- they're afk
+- it's really important
+- it's Laura(edited)

+
+0.8.2 - 2020-04-19
+- Examples: Update print_client_tls example to remove use of deprecated
+  OpenSSL functions.
+- Compatibility: Removes the use of make_shared in a number of cases where
+  it would be incompatible with newer versions of ASIO. Thank you Stefan
+  Floeren for the patch. #810 #814 #862 #843 #794 #808
+- CMake: Update cmake installer to better handle dependencies when using
+  g++ on MacOS. Thank you Luca Palano for reporting and a patch. #831
+- CMake: Update cmake installer to use a variable for the include directory
+  improving the ability of the install to be customized. THank you Schrijvers
+  Luc and Gianfranco Costamanga for reporting and a patch. #842
+
+0.8.1 - 2018-07-16
+Note: This release does not change library behavior. It only corrects issues
+in the installer and test system.
+- Test Suite: Adjust test suite to match behavior introduced in 0.8.0. Thank
+  you Gianfranco Costamagna for reporting and a patch. #731
+- CMake: Update cmake installer to only install library files globally.
+  Thank you Gianfraco Costamanga for reporting and a patch. #732
+
+0.8.0 - 2018-07-12
+- Examples: Add `print_client` example. This demonstrates a minimal non-TLS
+  client that connects to a server and prints out the messages it receives.
+- Examples: Add `print_client_tls` example. This demonstrates a minimal TLS
+  client, including basic support via Asio+OpenSSL for certificate chain
+  and hostname verification.
+- Feature: Add getter for all headers to the HTTP parsers. This allows a
+  wrapping library to enumerate all headers to send upstream. Thank you Jupp
+  Müller for reporting and an initial pull request.
+- Improvement: Move the `socket_init_handler` to execute as a part of `init_asio`
+  rather than connection `pre_init`. This allows setting of socket options prior
+  to the bind/listen/accept system calls. Thank you ChristianRobl3D for
+  reporting #530.
+- Improvement: Timers in transport integration tests should only fail if their
+  own test times out, rather than any test. #643 Thank you Alex Korotkin for
+  reporting and a patch.
+- Improvement: Preserve transport layer error codes in more cases, particularly
+  during calls to `endpoint::listen`. #652 Thank you vadz for reporting and
+  patches.
+- Compatibility: Make sure the chrono library used by Boost/Asio is in sync
+  with what the websocketpp is using. Thank you Flow86 for reporting and a
+  patch.
+- Compatibility: Update `telemetry_client` to use a slightly more cross platform
+  method of sleeping. Should work on windows now. Thank you Meir Yanovich for
+  reporting.
+- Compatibility: Updated permessage-deflate support to reflect that the zlib
+  library does not actually support a sliding window size of 256 bits. 
+  WebSocket++ will no longer negotiate 256 bit deflate windows. If the user
+  of the library tries to request a 256 bit window a 512 bit window will be
+  specified instead (This was the previous behavior). #596 #653 Thank you 
+  Vinnie Falco and Gianfranco Costamagna for reporting.
+- Compatibility: Better error handling and logging in cases where extension
+  requests parse correctly but negotiation fails.
+- Compatibility: Removed custom handling of `SSL_R_SHORT_READ` error condition.
+  This error code no longer exists in modern versions of OpenSSL and causes
+  a build error. It wasn't being used for anything particularly important
+  (slightly improving error reporting) and there isn't a great replacement.
+  #599 Thank you Gianfranco Costamagna for reporting.
+- Compatibility: Add missing `<stdint>` headers. Fixes issues with g++ 5.4.0.
+  #638 Thank you Alex Korotkin for reporting and a patch.
+- Compatibility: Remove the use of `std::auto_ptr` and `std::binary_function`
+  from builds with C++11 or later. These features are deprecated and were
+  removed entirely in C++17. This change allows building WebSocket++ on
+  C++17 compilers. #592 Thank you Michal Fojtak for reporting and a patch
+- Compatibility: Add 1014 close code and adds missing descriptions for codes
+  1012 and 1013. #589 Thank you jbwdevries and ronneke1996 for reporting and
+  patches.
+- Compatibility: Add hooks to support `mingw-std-threads` C++11 thread and mutex
+  polyfill library as an alternative to Boost. #608 Thank you Peter Taylor for
+  reporting and an initial patch.
+- Compatibility: Changed the handshake connection token to 'Upgrade' from
+  'upgrade'. Technically this header is supposed to be processed case
+  insensitively. In practice, there are browsers (such as Edge) that don't do
+  this and they tend to use the uppercase value used as an example in RFC6455.
+  Thank you Johann Bauer for reporting and a patch. #727
+- Bug: Store loggers in shared pointers to avoid crashes related to connections
+  trying to write logs entries after their respective endpoint has been
+  deallocated. Thank you Thalhammer for reporting and Jupp Müller for the 
+  patch. #539 #501
+- Bug: Change default listen backlog from 0 to `socket_base::max_connections`.
+  #549. Thank you derwassi and zwelab for reporting and na1pir for providing
+  access to hardware to debug the issue.
+- Bug: Fix a crash in the accept loop when `get_connection` fails. #551 Thank you
+  Walter Gray for a patch.
+- Bug/Documentation: Fix incorrect example code that used 
+  `websocketpp::lib::error_code` instead of `websocketpp::exception`. Thank you
+  heretic13 for reporting
+- Bug: Fix uninitialized shared pointer in Asio transport test suite. #647
+  Thank you Alex Korotkin for reporting and a patch.
+- Bug: Fix a thread safety issue in the permessage-deflate extension that
+  caused message corruption when sending compressed messages from a different
+  thread than the main I/O thread. #615 Thank you KyleNyenhuis and Pieter De 
+  Gendt for reporting and a patch.
+- Bug: Fix an undefined behavior issue performing a 64 bit wide shift on a 64
+  bit value. #636 Thank you Gregor Jasny for reporting and a patch
+- Bug: Fix some compile issues with ASIO_STANDALONE. #662 #665 Thank you
+  chronoxor and Guillaume Egles for reporting and patches.
+
+0.7.0 - 2016-02-22
+- MINOR BREAKING SOCKET POLICY CHANGE: Asio transport socket policy method 
+  `cancel_socket` will now return `lib::asio::error_code` instead of `void`.
+  Custom Asio transport socket policies will need to be updated accordingly.
+  This does not affect anyone using the bundled socket policies.
+- Feature: Basic support for the permessage-deflate extension. #344
+- Feature: Allow accessing the local endpoint when using the Asio transport.
+  This allows inspection of the address and port in cases where they are chosen
+  by the operating system rather than the user. Thank you Andreas Weis and 
+  Muzahid Hussain for reporting and related code. #458
+- Feature: Add support for subprotocols in Hybi00. Thank you Lukas Obermann
+  for reporting and a patch. #518
+- Feature: Adds `tcp_pre_bind handler` to Asio transport. This allows setting
+  arbitrary socket options after the listen acceptor has been created but before
+  the socket bind has been performed. #634 #439 Thank you Gregor Jasny for
+  the patch.
+- Improvement: Better automatic std::chrono feature detection for Visual Studio
+- Improvement: Major refactoring to bundled CMake build system. CMake can now be
+  used to build all of the examples and the test suite. Thank you Thijs Wenker
+  for a significant portion of this code. #378, #435, #449
+- Improvement: In build environments where `lib::error_code` and 
+  `lib::asio::error_code` match (such as using `boost::asio` with 
+  `boost::system_error` or standalone asio with `std::system_error`, transport
+  errors are passed through natively rather than being reported as a translated 
+  `pass_through` error type.
+- Improvement: Add a `get_transport_error` method to Asio transport connections
+  to allow retrieving a machine readable native transport error.
+- Improvement: Add `connection::get_response`, `connection::get_response_code`,
+  and `connection::get_response_msg` methods to allow accessing additional
+  information about the HTTP responses that WebSocket++ sends. #465 Thank you
+  Flow86 for reporting.
+- Improvement: Removes use of empty strings ("") in favor of `string::clear()`
+  and `string::empty()`. This avoids generating unnecessary temporary objects.
+  #468 Thank you Vladislav Yaroslavlev for reporting and a patch.
+- Documentation: Adds an example demonstrating the use of external `io_service`
+- Documentation: Adds a simple `echo_client` example.
+- Documentation: Begins migration of the web based user manual into Doxygen.
+- Bug: Fix memory leak when `init_asio` produces an error. #454 Thank you Mark 
+  Grimes for reporting and fixing.
+- Bug: Fix crash when processing a specially crafted HTTP header. Thank you Eli 
+  Fidler for reporting, test cases, and a patch. #456
+- Bug: Fix an issue where standalone Asio builds that use TLS would not compile
+  due to lingering boost code. #448 Thank you mjsp for reporting
+- Bug: Fix an issue where canceling a socket could throw an exception on some
+  older Windows XP platforms. It now prints an appropriate set of log messages
+  instead. Thank you Thijs Wenker for reporting and researching solutions. #460
+- Bug: Fix an issue where deferred HTTP connections that start sending a very 
+  long response before their HTTP handler ends would result in a second set of
+  HTTP headers being injected into the output. Thank you Kevin Smith for
+  reporting and providing test case details. #443
+- Bug: Fix an issue where the wrong type of strand was being created. Thank you 
+  Bastien Brunnenstein for reporting and a patch. #462
+- Bug: Fix an issue where TLS includes were broken for Asio Standalone builds.
+  Thank you giachi and Bastien Brunnenstein for reporting. #491
+- Bug: Remove the use of cached read and write handlers in the Asio transport.
+  This feature caused memory leaks when the `io_service` the connection was
+  running on was abruptly stopped. There isn't a clean and safe way of using
+  this optimization without global state and the associated locks. The locks
+  perform worse. Thank you Xavier Gibert for reporting, test cases, and code.
+  Fixes #490.
+- Bug: Fix a heap buffer overflow when checking very short URIs. Thank you 
+  Xavier Gibert for reporting and a patch #524
+- Compatibility: Fixes a number of build & config issues on Visual Studio 2015
+- Compatibility: Removes non-standards compliant masking behavior. #395, #469
+- Compatibility: Replace deprecated use of `auto_ptr` on systems where 
+  `unique_ptr` is available.
+
+0.6.0 - 2015-06-02
+- MINOR BREAKING TRANSPORT POLICY CHANGE: Custom transport policies will now be
+  required to include a new method `void set_uri(uri_ptr u)`. An implementation
+  is not required. The stub transport policy includes an example stub method
+  that can be added to any existing custom transport policy to fulfill this
+  requirement. This does not affect anyone using the bundled transports or
+  configs.
+- MINOR BREAKING SOCKET POLICY CHANGE: Custom asio transport socket policies 
+  will now be required to include a new method `void set_uri(uri_ptr u)`. Like
+  with the transport layer, an implementation is not required. This does not 
+  affect anyone using the bundled socket policies.
+- MINOR BREAKING DEPENDENCY CHANGE: When using Boost versions greater than or 
+  equal to 1.49 in C++03 mode, `libboost-chrono` is needed now instead of 
+  `libboost-date_time`. Users with C++11 compilers or using Boost versions 1.48
+  and earlier are not affected. Note: This change affects the bundled unit test
+  suite.
+- Feature: WebSocket++ Asio transport policy can now be used with the standalone
+  version of Asio (1.8.0+) when a C++11 compiler and standard library are 
+  present. This means that it is possible now to use WebSocket++'s Asio
+  transport entirely without Boost. Thank you Robert Seiler for proof of concept
+  code that was used as a guide for this implementation. Fixes #324 
+- Feature: Adds a vectored/scatter-gather write handler to the iostream
+  transport.
+- Feature: Adds the ability to defer sending an HTTP response until sometime
+  after the `http_handler` is run. This allows processing of long running http
+  handlers to defer their response until it is ready without blocking the
+  network thread. references #425
+- Improvement: `echo_server_tls` has been update to demonstrate how to configure
+  it for Mozilla's recommended intermediate and modern TLS security profiles.
+- Improvement: `endpoint::set_timer` now uses a steady clock provided by 
+  `boost::chrono` or `std::chrono` where available instead of the non-monotonic
+  system clock. Thank you breyed for reporting. fixes #241
+- Improvement: Outgoing TLS connections to servers using the SNI extension to
+  choose a certificate will now work. Thank you moozzyk for reporting. 
+  Fixes #400
+- Improvement: Removes an unnecessary mutex lock in `get_con_from_hdl`.
+- Cleanup: Asio transport policy has been refactored to remove many Boost
+  dependencies. On C++03 compilers the `boost::noncopyable` dependency has been
+  removed and the `boost::date_time` dependency has been replaced with the newer
+  `boost::chrono` when possible. On C++11 compilers the `boost::aligned_storage`
+  and `boost::date_time` dependencies are gone, replaced with equivalent C++11
+  standard library features.
+- Bug: Fixes a potential dangling pointer and inconsistent error message
+  handling in `websocketpp::exception`. #432 Thank you Tom Swirly for the fix.
+
+0.5.1 - 2015-02-27
+- Bug: Fixes an issue where some frame data was counted against the max header
+  size limit, resulting in connections that included a lot of frame data
+  immediately after the opening handshake to fail.
+- Bug: Fix a typo in the name of the set method for `max_http_body_size`. #406
+  Thank you jplatte for reporting.
+
+0.5.0 - 2015-01-22
+- BREAKING UTILITY CHANGE: Deprecated methods `http::parser::parse_headers`,
+  `http::response::parse_complete`, and `http::request::parse_complete` have
+  been removed.
+- Security: Disabled SSLv3 in example servers.
+- Feature: Adds basic support for accessing HTTP request bodies in the http
+  handler. #181
+- Feature: Adds the ability to register a shutdown handler when using the
+  iostream transport. This provides a clean interface for triggering the shut
+  down of external sockets and other cleanup without hooking in to higher level
+  WebSocket handlers.
+- Feature: Adds the ability to register a write handler when using the iostream
+  transport. This handler can be used to handle transport output in place of
+  registering an ostream to write to.
+- Feature: Adds a new logging policy that outputs to syslog. #386 Thank you Tom
+  Hughes for submitting the initial version of this policy.
+- Improvement: Message payload logging now prints text for text messages rather
+  than binary.
+- Improvement: Overhaul of handshake state machine. Should make it impossible
+  for exceptions to bubble out of transport methods like `io_service::run`.
+- Improvement: Overhaul of handshake error reporting. Fail handler error codes
+  will be more detailed and precise. Adds new [fail] and [http] logging channels
+  that log failed websocket connections and successful HTTP connections
+  respectively. A new aggregate channel package, `alevel::access_core`, allows
+  enabling connect, disconnect, fail, and http together. Successful HTTP
+  connections will no longer trigger a fail handler.
+- Improvement: Ability to terminate connection during an http handler to cleanly
+  suppress the default outgoing HTTP response.
+- Documentation: Add Sending & Receiving Messages step to chapter one of the
+  `utility_client` tutorial. Update `utility_client` example to match.
+- Cleanup: Removes unused files & STL includes. Adds required STL includes.
+  Normalizes include order.
+- Bug: Fixes a fatal state error when a handshake response is completed
+  immediately after that handshake times out. #389
+- Bug: MinGW fixes; C++11 feature detection, localtime use. #393 Thank you
+  Schebb for reporting, code, and testing.
+- Bug: Fixes an issue where `websocketpp::exception::what()` could return an out
+  of scope pointer. #397 Thank you fabioang for reporting.
+- Bug: Fixes an issue where endpoints were not reset properly after a call to
+  `endpoint::listen` failed. #390 Thank you wyyqyl for reporting.
+
+0.4.0 - 2014-11-04
+- BREAKING API CHANGE: All WebSocket++ methods now throw an exception of type
+  `websocketpp::exception` which derives from `std::exception`. This normalizes
+  all exception types under the standard exception hierarchy and allows
+  WebSocket++ exceptions to be caught in the same statement as others. The error
+  code that was previously thrown is wrapped in the exception object and can be
+  accessed via the `websocketpp::exception::code()` method.
+- BREAKING API CHANGE: Custom logging policies have some new required
+  constructors that take generic config settings rather than pointers to
+  std::ostreams. This allows writing logging policies that do not involve the
+  use of std::ostream. This does not affect anyone using the built in logging
+  policies.
+- BREAKING UTILITY CHANGE: `websocketpp::lib::net::htonll` and
+  `websocketpp::lib::net::ntohll` have been prefixed with an underscore to avoid
+  conflicts with similarly named macros in some operating systems. If you are
+  using the WebSocket++ provided 64 bit host/network byte order functions you
+  will need to switch to the prefixed versions.
+- BREAKING UTILITY CHANGE: The signature of `base64_encode` has changed from
+  `websocketpp::base64_encode(unsigned char const *, unsigned int)` to
+  `websocketpp::base64_encode(unsigned char const *, size_t)`.
+- BREAKING UTILITY CHANGE: The signature of `sha1::calc` has changed from
+  `websocketpp::sha1::calc(void const *, int, unsigned char *)` to
+  `websocketpp::sha1::calc(void const *, size_t, unsigned char *)`
+- Feature: Adds incomplete `minimal_server` and `minimal_client` configs that
+  can be used to build custom configs without pulling in the dependencies of
+  `core` or `core_client`. These configs will offer a stable base config to
+  future-proof custom configs.
+- Improvement: Core library no longer has std::iostream as a dependency.
+  std::iostream is still required for the optional iostream logging policy and
+  iostream transport.
+- Bug: C++11 Chrono support was being incorrectly detected by the `boost_config`
+  header. Thank you Max Dmitrichenko for reporting and a patch.
+- Bug: use of `std::put_time` is now guarded by a unique flag rather than a
+  chrono library flag. Thank you Max Dmitrichenko for reporting.
+- Bug: Fixes non-thread safe use of std::localtime. #347 #383
+- Compatibility: Adjust usage of std::min to be more compatible with systems
+  that define a min(...) macro.
+- Compatibility: Removes unused parameters from all library, test, and example
+  code. This assists with those developing with -Werror and -Wunused-parameter
+  #376
+- Compatibility: Renames ntohll and htonll methods to avoid conflicts with
+  platform specific macros. #358 #381, #382 Thank you logotype, unphased,
+  svendjo
+- Cleanup: Removes unused functions, fixes variable shadow warnings, normalizes
+  all whitespace in library, examples, and tests to 4 spaces. #376
+
+0.3.0 - 2014-08-10
+- Feature: Adds `start_perpetual` and `stop_perpetual` methods to asio transport
+  These may be used to replace manually managed `asio::io_service::work` objects
+- Feature: Allow setting pong and handshake timeouts at runtime.
+- Feature: Allows changing the listen backlog queue length.
+- Feature: Split tcp init into pre and post init.
+- Feature: Adds URI method to extract query string from URI. Thank you Banaan
+  for code. #298
+- Feature: Adds a compile time switch to asio transport config to disable
+  certain multithreading features (some locks, asio strands)
+- Feature: Adds the ability to pause reading on a connection. Paused connections
+  will not read more data from their socket, allowing TCP flow control to work
+  without blocking the main thread.
+- Feature: Adds the ability to specify whether or not to use the `SO_REUSEADDR`
+  TCP socket option. The default for this value has been changed from `true` to
+  `false`.
+- Feature: Adds the ability to specify a maximum message size.
+- Feature: Adds `close::status::get_string(...)` method to look up a human
+  readable string given a close code value.
+- Feature: Adds `connection::read_all(...)` method to iostream transport as a
+  convenience method for reading all data into the connection buffer without the
+  end user needing to manually loop on `read_some`.
+- Improvement: Open, close, and pong timeouts can be disabled entirely by
+  setting their duration to 0.
+- Improvement: Numerous performance improvements. Including: tuned default
+  buffer sizes based on profiling, caching of handler binding for async
+  reads/writes, non-malloc allocators for read/write handlers, disabling of a
+  number of questionably useful range sanity checks in tight inner loops.
+- Improvement: Cleaned up the handling of TLS related errors. TLS errors will
+  now be reported with more detail on the info channel rather than all being
+  `tls_short_read` or `pass_through`. In addition, many cases where a TLS short
+  read was in fact expected are no longer classified as errors. Expected TLS
+  short reads and quasi-expected socket shutdown related errors will no longer
+  be reported as unclean WebSocket shutdowns to the application. Information
+  about them will remain in the info error channel for debugging purposes.
+- Improvement: `start_accept` and `listen` errors are now reported to the caller
+  either via an exception or an ec parameter.
+- Improvement: Outgoing writes are now batched for improved message throughput
+  and reduced system call and TCP frame overhead.
+- Bug: Fix some cases of calls to empty lib::function objects.
+- Bug: Fix memory leak of connection objects due to cached handlers holding on to
+  reference counted pointers. #310 Thank you otaras for reporting.
+- Bug: Fix issue with const endpoint accessors (such as `get_user_agent`) not
+  compiling due to non-const mutex use. #292 Thank you logofive for reporting.
+- Bug: Fix handler allocation crash with multithreaded `io_service`.
+- Bug: Fixes incorrect whitespace handling in header parsing. #301 Thank you
+  Wolfram Schroers for reporting
+- Bug: Fix a crash when parsing empty HTTP headers. Thank you Thingol for
+  reporting.
+- Bug: Fix a crash following use of the `stop_listening` function. Thank you
+  Thingol for reporting.
+- Bug: Fix use of variable names that shadow function parameters. The library
+  should compile cleanly with -Wshadow now. Thank you giszo for reporting. #318
+- Bug: Fix an issue where `set_open_handshake_timeout` was ignored by server
+  code. Thank you Robin Rowe for reporting.
+- Bug: Fix an issue where custom timeout values weren't being propagated from
+  endpoints to new connections.
+- Bug: Fix a number of memory leaks related to server connection failures. #323
+  #333 #334 #335 Thank you droppy and aydany for reporting and patches.
+  reporting.
+- Compatibility: Fix compile time conflict with Visual Studio's MIN/MAX macros.
+  Thank you Robin Rowe for reporting.
+- Documentation: Examples and test suite build system now defaults to clang on
+  OS X
+
+0.3.0-alpha4 - 2013-10-11
+- HTTP requests ending normally are no longer logged as errors. Thank you Banaan
+  for reporting. #294
+- Eliminates spurious expired timers in certain error conditions. Thank you
+  Banaan for reporting. #295
+- Consolidates all bundled library licenses into the COPYING file. #294
+- Updates bundled sha1 library to one with a cleaner interface and more
+  straight-forward license. Thank you lotodore for reporting and Evgeni Golov
+  for reviewing. #294
+- Re-introduces strands to asio transport, allowing `io_service` thread pools to
+  be used (with some limitations).
+- Removes endpoint code that kept track of a connection list that was never used
+  anywhere. Removes a lock and reduces connection creation/deletion complexity
+  from O(log n) to O(1) in the number of connections.
+- A number of internal changes to transport APIs
+- Deprecates iostream transport `readsome` in favor of `read_some` which is more
+  consistent with the naming of the rest of the library.
+- Adds preliminary signaling to iostream transport of eof and fatal transport
+  errors
+- Updates transport code to use shared pointers rather than raw pointers to
+  prevent asio from retaining pointers to connection methods after the
+  connection goes out of scope. #293 Thank you otaras for reporting.
+- Fixes an issue where custom headers couldn't be set for client connections
+  Thank you Jerry Win and Wolfram Schroers for reporting.
+- Fixes a compile error on visual studio when using interrupts. Thank you Javier
+  Rey Neira for reporting this.
+- Adds new 1012 and 1013 close codes per IANA registry
+- Add `set_remote_endpoint` method to iostream transport.
+- Add `set_secure` method to iostream transport.
+- Fix typo in .gitattributes file. Thank you jstarasov for reporting this. #280
+- Add missing locale include. Thank you Toninoso for reporting this. #281
+- Refactors `asio_transport` endpoint and adds full documentation and exception
+  free varients of all methods.
+- Removes `asio_transport` endpoint method cancel(). Use `stop_listen()` instead
+- Wrap internal `io_service` `run_one()` method
+- Suppress error when trying to shut down a connection that was already closed
+
+0.3.0-alpha3 - 2013-07-16
+- Minor refactor to bundled sha1 library
+- HTTP header comparisons are now case insensitive. #220, #275
+- Refactors URI to be exception free and not use regular expressions. This
+  eliminates the dependency on boost or C++11 regex libraries allowing native
+  C++11 usage on GCC 4.4 and higher and significantly reduces staticly built
+  binary sizes.
+- Updates handling of Server and User-Agent headers to better handle custom
+  settings and allow suppression of these headers for security purposes.
+- Fix issue where pong timeout handler always fired. Thank you Steven Klassen
+  for reporting this bug.
+- Add ping and pong endpoint wrapper methods
+- Add `get_request()` pass through method to connection to allow calling methods
+  specific to the HTTP policy in use.
+- Fix issue compile error with `WEBSOCKETPP_STRICT_MASKING` enabled and another
+  issue where `WEBSOCKETPP_STRICT_MASKING` was not applied to incoming messages.
+  Thank you Petter Norby for reporting and testing these bugs. #264
+- Add additional macro guards for use with boost_config. Thank you breyed
+  for testing and code. #261
+
+0.3.0-alpha2 - 2013-06-09
+- Fix a regression that caused servers being sent two close frames in a row
+  to end a connection uncleanly. #259
+- Fix a regression that caused spurious frames following a legitimate close
+  frames to erroneously trigger handlers. #258
+- Change default HTTP response error code when no http_handler is defined from
+  500/Internal Server Error to 426/Upgrade Required
+- Remove timezone from logger timestamp to work around issues with the Windows
+  implementation of strftime. Thank you breyed for testing and code. #257
+- Switch integer literals to char literals to improve VCPP compatibility.
+  Thank you breyed for testing and code. #257
+- Add MSVCPP warning suppression for the bundled SHA1 library. Thank you breyed
+  for testing and code. #257
+
+0.3.0-alpha1 - 2013-06-09
+- Initial Release

+WebSocket++ (0.8.2)
+==========================
+
+WebSocket++ is a header only C++ library that implements RFC6455 The WebSocket
+Protocol. It allows integrating WebSocket client and server functionality into
+C++ programs. It uses interchangeable network transport modules including one
+based on raw char buffers, one based on C++ iostreams, and one based on Asio 
+(either via Boost or standalone). End users can write additional transport
+policies to support other networking or event libraries as needed.
+
+Major Features
+==============
+* Full support for RFC6455
+* Partial support for Hixie 76 / Hybi 00, 07-17 draft specs (server only)
+* Message/event based interface
+* Supports secure WebSockets (TLS), IPv6, and explicit proxies.
+* Flexible dependency management (C++11 Standard Library or Boost)
+* Interchangeable network transport modules (raw, iostream, Asio, or custom)
+* Portable/cross platform (Posix/Windows, 32/64bit, Intel/ARM/PPC)
+* Thread-safe

+/// Transport policies provide network connectivity and timers
+/**
+ * ### Connection Interface
+ *
+ * Transport connection components needs to provide:
+ *
+ * **init**\n
+ * `void init(init_handler handler)`\n
+ * Called once shortly after construction to give the policy the chance to
+ * perform one time initialization. When complete, the policy must call the
+ * supplied `init_handler` to continue setup. The handler takes one argument
+ * with the error code if any. If an error is returned here setup will fail and
+ * the connection will be aborted or terminated.
+ *
+ * WebSocket++ will call init only once. The transport must call `handler`
+ * exactly once.
+ *
+ * **async_read_at_least**\n
+ * `void async_read_at_least(size_t num_bytes, char *buf, size_t len,
+ * read_handler handler)`\n
+ * start an async read for at least num_bytes and at most len
+ * bytes into buf. Call handler when done with number of bytes read.
+ *
+ * WebSocket++ promises to have only one async_read_at_least in flight at a
+ * time. The transport must promise to only call read_handler once per async
+ * read.
+ *
+ * **async_write**\n
+ * `void async_write(const char* buf, size_t len, write_handler handler)`\n
+ * `void async_write(std::vector<buffer> & bufs, write_handler handler)`\n
+ * Start a write of all of the data in buf or bufs. In second case data is
+ * written sequentially and in place without copying anything to a temporary
+ * location.
+ *
+ * Websocket++ promises to have only one async_write in flight at a time.
+ * The transport must promise to only call the write_handler once per async
+ * write
+ *
+ * **set_handle**\n
+ * `void set_handle(connection_hdl hdl)`\n
+ * Called by WebSocket++ to let this policy know the hdl to the connection. It
+ * may be stored for later use or ignored/discarded. This handle should be used
+ * if the policy adds any connection handlers. Connection handlers must be
+ * called with the handle as the first argument so that the handler code knows
+ * which connection generated the callback.
+ *
+ * **set_timer**\n
+ * `timer_ptr set_timer(long duration, timer_handler handler)`\n
+ * WebSocket++ uses the timers provided by the transport policy as the
+ * implementation of timers is often highly coupled with the implementation of
+ * the networking event loops.
+ *
+ * Transport timer support is an optional feature. A transport method may elect
+ * to implement a dummy timer object and have this method return an empty
+ * pointer. If so, all timer related features of WebSocket++ core will be
+ * disabled. This includes many security features designed to prevent denial of
+ * service attacks. Use timer-free transport policies with caution.
+ *
+ * **get_remote_endpoint**\n
+ * `std::string get_remote_endpoint()`\n
+ * retrieve address of remote endpoint
+ *
+ * **is_secure**\n
+ * `void is_secure()`\n
+ * whether or not the connection to the remote endpoint is secure
+ *
+ * **dispatch**\n
+ * `lib::error_code dispatch(dispatch_handler handler)`: invoke handler within
+ * the transport's event system if it uses one. Otherwise, this method should
+ * simply call `handler` immediately.
+ *
+ * **async_shutdown**\n
+ * `void async_shutdown(shutdown_handler handler)`\n
+ * Perform any cleanup necessary (if any). Call `handler` when complete.
