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);
