Look at killpg().  Or use the negative of the process group number as
the process ID.  Or do you mean something else by "process group"?

If you reall want to dig this out of the kernel, you'll need to play
games with nlist and /dev/kmem the way ps does.

getppid() gets the process ID of the parent of *its caller*.  It can't
be used to obtain the parent process ID of any other process.
