Autolock solves the problem of forgetting to unlock after locking

   You can include this in classes that use mutexes AutoLock class

   The principle is very simple , AutoLock Class object locks the mutex passed in during construction , Unlock the mutex when destructing , such Test Class Fun The function is locked , And we don't have to worry about forgetting to unlock , In addition, if you don't want to give the whole Fun Lock , You can construct where you need to start locking AutoLock object , If it is necessary to Fun Unlocking before the end of the function can also be done through new delete AutoLock Object to implement , But that's not as good as using it directly EnterCriticalSection as well as LeaveCriticalSection 了 , lost AutoLock The meaning of .

class AutoLock { public: AutoLock(CRITICAL_SECTION& cs) : cs_(cs) { EnterCriticalSection(&cs_); } ~AutoLock() { LeaveCriticalSection(&cs_); } private: CRITICAL_SECTION& cs_; }; class Test { public: Test() { InitializeCriticalSection(&m_cs); } void Fun() { /* EnterCriticalSection(&m_cs); //do your things... LeaveCriticalSection(&m_cs); */ AutoLock lock(m_cs); //do your things... } private: CRITICAL_SECTION m_cs; };
