zmq_msg_init - initialise empty 0MQ message
int zmq_msg_init (zmq_msg_t *msg);
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. |
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.
No errors are defined.
zmq_msg_t msg; rc = zmq_msg_init (&msg); assert (rc == 0); rc = zmq_recv (socket, &msg, 0); assert (rc == 0);
