Qt 3 Support Members for QMutexThe following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code. Public FunctionsMember Function DocumentationQMutex::QMutex ( bool recursive )Use the constructor that takes a RecursionMode parameter instead. bool QMutex::locked ()Returns true if the mutex is locked by another thread; otherwise returns false. It is generally a bad idea to use this function, because code that uses it has a race condition. Use tryLock() and unlock() instead. For example, if you have code like bool isLocked = mutex.locked(); you can rewrite it as bool isLocked = true; if (mutex.tryLock()) { mutex.unlock(); isLocked = false; }
