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.

NAME

       zmq_msg_init - initialise empty 0MQ message

SYNOPSIS

       int zmq_msg_init (zmq_msg_t *msg);

DESCRIPTION

       The zmq_msg_init() function shall initialise the message object referenced by msg to represent an empty message. This function is most
       useful when called before receiving a message with zmq_recv().

	   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() and zmq_msg_init_size() are mutually exclusive. Never initialize the same zmq_msg_t
	   twice.

RETURN VALUE

       The zmq_msg_init() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.

ERRORS

       No errors are defined.

EXAMPLE

       Receiving a message from a socket.

	   zmq_msg_t msg;
	   rc = zmq_msg_init (&msg);
	   assert (rc == 0);
	   rc = zmq_recv (socket, &msg, 0);
	   assert (rc == 0);
