NAME
|
|
----
|
|
zmq_msg_move - move content of a message to another message
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
*int zmq_msg_move (zmq_msg_t '*dest', zmq_msg_t '*src');*
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
The _zmq_msg_move()_ function shall move the content of the message object
|
|
referenced by 'src' to the message object referenced by 'dest'. No actual
|
|
copying of message content is performed, 'dest' is simply updated to reference
|
|
the new content. 'src' becomes an empty message after calling _zmq_msg_move()_.
|
|
The original content of 'dest', if any, shall be released.
|
|
|
|
CAUTION: Never access 'zmq_msg_t' members directly, instead always use the
|
|
_zmq_msg_ family of functions.
|
|
|
|
|
|
RETURN VALUE
|
|
------------
|
|
The _zmq_msg_move()_ function shall return zero if successful. Otherwise it
|
|
shall return `-1` and set 'errno' to one of the values defined below.
|
|
|
|
|
|
ERRORS
|
|
------
|
|
*EFAULT*::
|
|
Invalid message.
