说明：  C++ 创建线程互斥对象的实例源码下载，声明线程函数，创建线程，程序睡眠，释放互斥对象，设置事件对象为无信号状态，生成控制台程序，仅供参考。
(C++ to create an instance of the thread mutex source download, declare the thread function, create a thread, the program sleep, release the mutex object, set the event object to non-signal state, generate console application for reference purposes only.)
