Hi all

I tried to use sem_init() but I think it is not there to use. It is
declared in semaphore.h but when I do man sem_init() then it gives the
message "No manual entry for sem_init".

Now, I am using sem_open(). I think it is right API to create unique
semaphore between multi-processes. But creating it in one process if I
try to create in another process, the value of semaphore is not same.
I am using same name in both process(1st argument of sem_open()).

Please suggest to create semaphore (cross-processes).


POSIX unnamed semaphores are not supported.

Use either POSIX named semaphores, or use System V semaphores:

	man sem_open
	man semget
