使用ZeroMQ消息的线程间通信

Question

我试图zeroMQ用作在多个线程之间实现消息传递系统的方法.我尝试了下面的代码,但它不起作用; 具体而言zmq_recv,每个线程中的调用不会等待/阻止任何消息被执行.

你能帮我解决这段代码吗？

我正在使用Linux OS和gcc

最好的祝福

    static void *
    worker_routine (void *context) {
        // Socket to talk to dispatcher
        void *receiver = zmq_socket (context, ZMQ_REP);
        zmq_connect (receiver, "inproc://workers");
        while (1) {

            zmq_msg_t request;
            zmq_msg_init( &request );
            zmq_recv( receiver, &request, 0 );
            printf ("Received request\n");
            // Do some 'work'
            usleep (1000);
            // Send reply back to client
            zmq_send (receiver, &request, 0);
        }
        zmq_close (receiver);
        return NULL;
    }

    int main (void) {

    void *context = zmq_init (1);
    void *clients = zmq_socket (context, ZMQ_REP);
    zmq_bind (clients, "inproc://workers");

    int thread_nbr;
    for (thread_nbr = 0; thread_nbr < 5; thread_nbr++) {
        pthread_t worker;
        pthread_create (&worker, NULL, worker_routine, context);
    }

    zmq_close (clients);
    zmq_term (context);
    return 0;
    }

两个套接字都是REP.你想要的是REQ + REP.
