|
NAME
|
||
|
|
----
|
||
|
|
zmq_msg_init_buffer - initialise 0MQ message with buffer copy
|
||
|
|
|
||
|
|
|
||
|
|
SYNOPSIS
|
||
|
|
--------
|
||
|
|
*int zmq_msg_init_buffer (zmq_msg_t '*msg', const void '*buf', size_t 'size');*
|
||
|
|
|
||
|
|
|
||
|
|
DESCRIPTION
|
||
|
|
-----------
|
||
|
|
The _zmq_msg_init_buffer()_ function shall allocate any resources required to
|
||
|
|
store a message 'size' bytes long and initialise the message object referenced
|
||
|
|
by 'msg' to represent a copy of the buffer referenced by the 'buf' and
|
||
|
|
'size' arguments.
|
||
|
|
|
||
|
|
The implementation shall choose whether to store message content on the stack
|
||
|
|
(small messages) or on the heap (large messages).
|
||
|
|
|
||
|
|
CAUTION: Never access 'zmq_msg_t' members directly, instead always use the
|
||
|
|
_zmq_msg_ family of functions.
|
||
|
|
|
||
|
|
CAUTION: The functions _zmq_msg_init()_, _zmq_msg_init_data()_,
|
||
|
|
_zmq_msg_init_buffer()_ and _zmq_msg_init_buffer()_ are mutually exclusive.
|
||
|
|
Never initialise the same 'zmq_msg_t' twice.
|
||
|
|
|
||
|
|
|
||
|
|
RETURN VALUE
|
||
|
|
------------
|
||
|
|
The _zmq_msg_init_buffer()_ function shall return zero if successful. Otherwise
|
||
|
|
it shall return `-1` and set 'errno' to one of the values defined below.
|
||
|
|
|
||
|
|
|
||
|
|
