The semop, semget, semctl family implement System V semaphores. ipcs and ipcrm only view and delete System V objects. I don't know of any way to view what POSIX semaphores are in existence. And from memory, you're using the POSIX routines, hence nothing from ipcs. I think I led you down the wrong path with ipcs!

I want to determine how many active semaphores are on my system, and I'm not sure how this can be done. It seems I can know how many semaphores are allowed by using the sysctl command. Someone had suggested that the ipcs command would be helpful. When I use it like this: ipcs -as This is the output I get, which I don't find to be helpful: Semaphores: T ID KEY MODE OWNER GROUP CREATOR CGROUP NSEMS OTIME CTIME What command can give me the information I am seeking?
