windows客户端开发--实现一个多线程定时器

旧城等待， 2022-06-16 09:44 163阅读 0赞

go了很久了，但是生活还得继续，工作还得继续，今天跟大家分享一个多线程的定时器。

**Windows为我们提供了SetTimer和KillTimer**  
启动  
SetTimer(m\_hWnd, TESTWM\_SENDDING\_EMAIL\_TIMER, 500, NULL);

响应  
然后响应uMsg == TESTWM\_SENDDING\_EMAIL\_TIMER

销毁  
KillTimer(m\_hWnd, TESTWM\_SENDDING\_EMAIL\_TIMER);

**实现一个多线程定时器**  
这里用标准C++写的，包括了一些C++11特性。

基本的知识之前的博客都有介绍：

言归正传，实现一个多线程定时器：

#ifndef TIMER_H_
    #define TIMER_H_
    
    #include <thread>
    #include <chrono>
    
    class Timer
    {
        std::thread th;
        bool running = false;
    
    public:
        typedef std::chrono::milliseconds Interval;
        typedef std::function<void(void)> Timeout;
    
        void start(const Interval &interval,
            const Timeout &timeout)
        {
            running = true;
    
            th = std::thread([=]()
            {
                while (running == true) {
                    std::this_thread::sleep_for(interval);
                    timeout();
                }
            });
    
        }
    
        void stop()
        {
            running = false;
            if (th.joinable())
            {
                th.join();
            }
        }
    };
    
    #endif // TIMER_H_
