xs_msg_init (3)

int xs_msg_init (xs_msg_t *msg);

The xs_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 xs_recv().

Caution

Never access xs_msg_t members directly, instead always use the xs_msg family of functions.

Caution

The functions xs_msg_init(), xs_msg_init_data() and xs_msg_init_size() are mutually exclusive. Never initialize the same xs_msg_t twice.

The xs_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.

Receiving a message from a socket.

xs_msg_t msg;
rc = xs_msg_init (&msg);
assert (rc == 0);
rc = xs_recv (socket, &msg, 0);
assert (rc == 0);
