Lock, mutex, semaphore… what's the difference?
... that's locked and the lock is not shared with any other processes.
A mutex is the same as a lock but it can be system wide (shared by multiple processes).
A semaphore does the same as a mutex but allows x number of threads to enter, this can be used for example to limit the number of cpu, io or r...

When it comes to strings, QString offers much more complete functionality ...
