QMutexLocker - locking question

[Dariusz]

Hey

So I have a QMutexLocker l(&mLock);

When this function gets called and mLock is already locked by another thread. What happens?

1. The program stops & try-lock/wait forever until he can access the mutex to lock it?
2. The program stops and does nothing.

I'm trying to debug app locks :- )

TIA!

@Dariusz
I assume it does as per QMutextLocker::lock(), i.e. block and wait.

[Dariusz]

So if its already locked, then it waits? Will it try again locking or its just in waiting mode?

@Dariusz
I believe it will block/wait and then lock and continue as & when the mutex gets unlocked. But you should test.

This is exactly what a mutex is build for...
