I am using visual C++ 2003 in windows XP. I need semaphore in my program, what API should I use for that? What is the most updated and recomended API I should use? Is semaphore not a standard user program service in windows? What should I use instead? Thanks in advance.

I have found the create_semaphore and wait, but how do I do signal to the semaphore?

ReleaseSemaphore
WaitForSingleObjetc

All of which are linked from the CreateSemaphore page.

Ok, actually I have already seen it, but I didnt notice that the release semaphore is actually the signal mechanisem.
Thanks

Another question, don't I need to release the HANDLE somewhere? how do I release it?

just a FYI: the Boost.Threads library is pretty slick

You can release it with CloseHandle.
