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);
