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.Originally Posted by tbscope
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.
