本节演示使用多线程的代码

由于示例中使用的是pthead函数 为了在windows下运行 我做了点改动

使用c++11 的thread函数

代码如下 与第一节的hwclient 配套使用

// mttest.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include "zhelpers.hpp"
#include <thread>

void worker_routine(void* arg)
{
    zmq::context_t *context = (zmq::context_t *) arg;

    zmq::socket_t socket(*context, ZMQ_REP);
    socket.connect("inproc://workers");

    while ()
    {
        zmq::message_t request;
        socket.recv(&request);
        std::cout << "Received request: [" << (char*)request.data() << "]" << std::endl;

        //  Do some 'work'
        Sleep();

        //  Send reply back to client
        zmq::message_t reply();
        memcpy((void *)reply.data(), "World", );
        socket.send(reply);
    }
    return;
}

int main()
{
    zmq::context_t context();
    zmq::socket_t clients(context, ZMQ_ROUTER);
    clients.bind("tcp://*:5555");
    zmq::socket_t workers(context, ZMQ_DEALER);
    workers.bind("inproc://workers");

    std::thread t[];
    for (int thread_nbr = ; thread_nbr < ; thread_nbr++)
    {
        t[thread_nbr] = std::thread(worker_routine, (void *)&context);
    }

    zmq::proxy(clients, workers, NULL);

    for (int thread_nbr = ; thread_nbr < ; thread_nbr++)
    {
        t[thread_nbr].join();
    }

    return ;
}

// temp.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include "zhelpers.hpp"
#include <thread>
void step1(void *arg) {

    zmq::context_t * context = static_cast<zmq::context_t*>(arg);

    //  Signal downstream to step 2
    zmq::socket_t sender(*context, ZMQ_PAIR);
    sender.connect("inproc://step2");

    s_send(sender, "");

    return;
}

//  Step 2 relays the signal to step 3

void step2(void *arg) {

    zmq::context_t * context = static_cast<zmq::context_t*>(arg);

    //  Bind to inproc: endpoint, then start upstream thread
    zmq::socket_t receiver(*context, ZMQ_PAIR);
    receiver.bind("inproc://step2");

    std::thread t = std::thread(step1, context);

    //  Wait for signal
    s_recv(receiver);

    //  Signal downstream to step 3
    zmq::socket_t sender(*context, ZMQ_PAIR);
    sender.connect("inproc://step3");
    s_send(sender, "");

    t.join();
    return;
}

int main()
{
    zmq::context_t context();

    //  Bind to inproc: endpoint, then start upstream thread
    zmq::socket_t receiver(context, ZMQ_PAIR);
    receiver.bind("inproc://step3");

    std::thread t = std::thread(step2, &context);

    //  Wait for signal
    s_recv(receiver);

    std::cout << "Test successful!" << std::endl;

    t.join();
    return ;
}
