To further clarify, what I need to be able to do is find out if the processes my program spawns has terminated (without cleaning them up). After I know the process is done, I need to signal the rest of the process group to clear out any processes it may have spawned (that haven't changed to a new process group). I can't use waitpid () to find out if the process has quit and then signal the process group.

[what I think you omitted]... because once you do the the waitpid() to detect the process is gone, the process group tied to that pid is [potentially] gone and, even worse, potentially recycled. Is that your concern?

If so, you can use kevent(2) to get notified of the process termination, send your process group signal, and then reap the child.
