线程同步

创建线程：

    DWORD param;    LPDWORD dwThreadID;  //线程ID    //创建线程    HANDLE hThread = CreateThread(        NULL,    //安全设置，一般设为NULL        0,       //新线程的初始堆栈大小，默认0        (LPTHREAD_START_ROUTINE)ThreadFunction,  //指向线程函数        &param,  //传递给ThreadProc的参数，这样主线程和从属线程就可以共享数据。        0,       //启动选项，一般为0        &dwThreadID);  //存储线程ID    if(hThread == INVALID_HANDLE_VALUE)    {        MessageBox("线程创建失败！", "提示", 64);        return;    }
