ZMQ_MSG_INIT(3) 0MQ Manual ZMQ_MSG_INIT(3) 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); SEE ALSO zmq_msg_init_size(3) zmq_msg_init_buffer(3) zmq_msg_init_data(3) zmq_msg_close(3) zmq_msg_data(3) zmq_msg_size(3) zmq(7) AUTHORS This page was written by the 0MQ community.
