binary semaphore with NON-busy waiting

[stephaniei447]

can someone please help me on how will I be able to program this?

So, say I have a process and its placed into the binary semaphore, I can't have the same process be placed into the same binary semaphore or any other binary semaphore right? Or can I?

In C++11 (and boost) there is no semaphore but mutex:

Use a recursive_mutex if you want to lock it multiple times for the same thread:
