Hi,

I need to synchronize 2 threads, that is once one is done doing  
something, it should activate another thread that had been waiting in  
a pending state.
I see the thread library offers mutexes and nothing else. I guess  
mutexes would do, but I do not believe I should use mutexes for my  
application. Mutexes are supposed to provide mutual exclusion when  
critical data is accessed. Semaphores should be used for what I want  
to do.

However, I only see semaphores available in the interprocess library.  
I only need inter-thread synchronization, and going the long way with  
the interprocess library seems a bit overkill.

It may be an ideology issue here. I would appreciate your comments on  
what to use in this case.

Thanks,
Jean
