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.
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
Example 1. 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);
