Interprocess nonblocking semaphore / mutex / shared memory.

[m.p]

Hello!

I need lock some resources (e.g. files) used by my programs. I've got few process and I want synchronize beetwen them. QSystemSemaphore or QSharedMemory look nice, but unfortunetly those classes don't have non-blocking function to lock (like QMutex's tryLock() ). Could anyone pass me a nice multiplatform solution for that?

best regards
