zmq_atomic_counter_value(3)
===========================
NAME
----
zmq_atomic_counter_value - return value of atomic counter
SYNOPSIS
--------
*int zmq_atomic_counter_value (void *counter);*
DESCRIPTION
-----------
The _zmq_atomic_counter_value_ function returns the value of an atomic
counter created by _zmq_atomic_counter_new()_. This function uses platform
specific atomic operations.
RETURN VALUE
------------
The _zmq_atomic_counter_value()_ function returns the value of the
atomic counter. If _counter_ does not point to an atomic counter created by
_zmq_atomic_counter_new()_, the behaviour is undefined.
EXAMPLE
-------
.Test code for atomic counters
----
void *counter = zmq_atomic_counter_new ();
assert (zmq_atomic_counter_value (counter) == 0);
assert (zmq_atomic_counter_inc (counter) == 0);
assert (zmq_atomic_counter_inc (counter) == 1);
assert (zmq_atomic_counter_inc (counter) == 2);
assert (zmq_atomic_counter_value (counter) == 3);
assert (zmq_atomic_counter_dec (counter) == 1);
assert (zmq_atomic_counter_dec (counter) == 1);
assert (zmq_atomic_counter_dec (counter) == 0);
zmq_atomic_counter_set (counter, 2);
assert (zmq_atomic_counter_dec (counter) == 1);
assert (zmq_atomic_counter_dec (counter) == 0);
zmq_atomic_counter_destroy (&counter);
return 0;
