int zmq_recvmsg (void '*socket', zmq_msg_t '*msg', int 'flags');
該api用於接收消息, 其具體用法與zmq_recv 一致.
example:
/* Create an empty 0MQ message */
zmq_msg_t msg;
int rc = zmq_msg_init (&msg);
assert (rc == 0);
/* Block until a message is available to be received from socket */
rc = zmq_recvmsg (socket, &msg, 0);
assert (rc != -1);
/* Release message */
zmq_msg_close (&msg);
----
.Receiving a multi-part message
----
int64_t more;
size_t more_size = sizeof (more);
do {
/* Create an empty 0MQ message to hold the message part */
zmq_msg_t part;
int rc = zmq_msg_init (&part);
assert (rc == 0);
/* Block until a message is available to be received from socket */
rc = zmq_recvmsg (socket, &part, 0);
assert (rc != -1);
/* Determine if more message parts are to follow */
rc = zmq_getsockopt (socket, ZMQ_RCVMORE, &more, &more_size);
assert (rc == 0);
zmq_msg_close (&part);
} while (more);
