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);
