In the qt libs there exists the possibility to create a mutex shared between two or more process?

I'm searching something with the function tryLock() (similar to the function described in the QMutex class).

Tnx.

Yes and No.

No: I'm searching for something with the tryLock() member function.
The tryLock() function exits immediately by returning false if the Mutex is locked.

Yes: It's shared between two or more process.

Not in my case.

But it's also possible to implement a traLock() function starting from the QSharedMemory.
If there's not any others solution.
