Now I'm confused because I assumed that if Program B spawned Program C
that Program B's PID (process ID) would be the PPID (parent process ID)
to Program C.
I also thought that if Program B was killed, that killing the parent
would kill the child (Program C).
In which case, wouldn't it be easier to just have Program B check for a
condition (created by Program A - like the existance of a file or
something) after Program C completed and exit itself if that condition
was true?
Or am I missing something here? If so, please correct me!
