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_msg_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() , zmq_msg_init_size() and zmq_msg_init_buffer() are mutually exclusive. Never initialise the same zmq_msg_t twice.
RETURN VALUE
The zmq_msg_init() function always returns zero.
ERRORS
No errors are defined.
EXAMPLE
Receiving a message from a socket .
zmq_msg_t msg;
rc = zmq_msg_init (&msg);
assert (rc == 0);
int nbytes = zmq_msg_recv (socket, &msg, 0);
assert (nbytes != -1);
