c++ - boost 线程卡在 _endthreadex

Question

我想我犯了一个简单的错误，但由于我注意到这里有很多 boost 专家，所以我想我会寻求帮助。

我正在尝试在 Windows XP 上使用 boost threads(1_40)。主程序加载一个dll，像这样启动线程(注意这不是在一个类中，静态并不意味着对类静态而是对文件私有(private))。

static boost::thread network_thread;
static bool quit = false;
HANDLE quitEvent;

//some code omitted for clarity, ask if you think it would help
void network_start()
{
  HANDLE *waitHandles = (HANDLE*)malloc(3 * sizeof(HANDLE));
  waitHandles[0] = quitEvent;
  waitHandles[1] = recvEvent;
  waitHandles[2] = pendingEvent;
  do {
      //read network stuff, or quit event
      dwEvents =WaitForMultipleObjects(3, waitHandles, FALSE, timeout);
   } while (!quit)
}

DllClass::InitInstance() 
{
}

DllClass::ExportedFunction()
{
   network_thread = boost::thread(boost::bind<void>(network_start));
}


DllClass::ExitInstance()
{
  //signal quit (which works)
   quit = true;
   SetEvent(QuitEvent);
   //the following code is slightly verbose because I'm trying to figure out what's wrong
    try {
       if (network_thread.joinable() ) {
           network_thread.join();
         } else {
            TRACE("Too late!");
        }
   } catch (boost::thread_interrupted&) {
        TRACE("NET INTERRUPTED");
    }
}

问题是主线程卡在join上，网络线程卡在_endthreadex的最后。我误会了什么？

您不应该在 InitInstance/ExitInstance 中创建/结束线程，
