The 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.
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; }
