std::bind(&GameServer::process_thread,this)返回一个std::function,绑定成员函数process_thread,然后new std::thread(std::Funciton)返回thread* reset源码这样的 template<class_Ux>voidreset(_Ux *_Px) {//release, take ownership of _P

我们经常会在子线程函数中写一个while循环去处理队列任务,当任务全部处理完成之后需要挂起线程,减少CPU负载,所以对应这个需求对std::thread进行了封装,实现一个扩展的std::thread基类,在基类中提供开启线程、暂停线程、唤起线程、停止线程的函数,并提供一个纯虚函数接口CustomRun,用于在子类中扩展自己的线程处理函数。
unsigned int increment() { std::unique_lock lock(mutex_); return ++value_; } // Only one thread/writer can reset/write the counter's value. void reset() { std::unique_lock lock(mutex_); value_ = 0; } private: mutable std::shared_mutex mutex_; unsigned int value_ = 0; }; ...
