boost::condition_variableboost::time_wait使用方法

　　boost 的线程库不能强行终止，所以通过 time_wait 可以让其自然的结束。

// BoostTest.cpp : 定义控制台应用程序的入口点。

using namespace std;
using namespace boost;

boost::mutex test_mutex;  
boost::condition_variable test_condition;

    for (;;)

        if (test_condition.timed_wait(lock, get_system_time() + posix_time::seconds(3)))   
        
            cout << "成功接收到通知" << endl; //这里加个break就结束了  
        
        else   
        
            cout << "没有等待到通知" << endl;  
        
    


int _tmain(int argc, _TCHAR* argv[])

    boost::thread test_thread(test);  

    for (;;)   
      
        ::system("PAUSE");  
        cout << "开始发送通知" << endl;  
        test_condition.notify_one();  
      

    return 0;
