互斥对象是系统内核维护的一种数据结构，保证了对象对单个线程的访问权。
创建互斥对象：
HANDLE CreateMutex(
LPSECURITY_ATTRIBUTES lpMutexAttributes, 安全属性结构指针，可为NULL,表示默认安全性
BOOL bInitialOwner, //是否占有该互斥量，TRUE：占有，FALSE：不占有
LPCTSTR lpName //设置互斥对象的名字
);
获得互斥对象：
DWORD WaitForSingleObject(
HANDLE hHandle， //互斥对象的句柄
DWORD dwMilliseconds //0：测试对象的状态立即返回；INFINITE：对象被触发信号后，函数才会返回
}
释放互斥对象：
BOOL ReleaseMutex(HANDLE hHandle)
