C++11写watchdog

最近被问到怎么用C++11写watchdog，考虑了一会儿，答对了思路，但是没能写出来。于是去翻了下chatgpt，看了几眼后自己尝试写了下，代码如下，权当存档

#include <thread>
#include <atomic>
#include <iostream>

class WatchDog
{
public:
    WatchDog(int count, int interval)
        : m_count(count), m_interval(interval)
    {

    }

    ~WatchDog()
    {
        if (m_thread.joinable())
        {
            m_thread.join();
        }
    }

    void start()
    {
        if (m_run)
        {
            return;
        }
        m_run = true;
        m_thread = std::thread([this]()
            {
                int count = 0;
                while (m_run)
                {
                    std::this_thread::sleep_for(std::chrono::seconds(m_interval));
                    if (!m_reset)
                    {
                        ++count;
                        if (count > m_count)
                        {
