zmq_msg_move(3)
===============
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.
