我用sleep语句的时候报错【未定义对sleep的引用】,网上找到的信息有的人说【mingw舍弃了sleep函数】,有的人说【使用windows api函数 Sleep或者c++11 标准新增加的this_thread::sleep_for()】,有的人说【mingw下的sleep问题:SetErrorMode、Beep和Sleep三个函数舍弃了,可以使用win32 API对应的函数】。。。 可我真心...

C++11开始引入了多线程库<thread>,其中也包含了互斥锁的API:std::mutex 头文件:< mutex > 类型: std::mutex 用法:在C++中,通过构造std::mutex的实例创建互斥元,调用成员函数lock()来锁定它,调用unlock()来解锁,不过一般不推荐这种做法,标准C++库提供了std::lock_guard类模板,实现了互斥元的RAII惯用语法。std...
