setpgrp-problems

I have designed an autooperating facility for UNIX-systems. By controlling
some processes, there is a problem in using the function setpgrp.
What I'll need is a function to create a process group in order to send
the leader of the process group via kill a signal and all members of that
group should get the signal.
The effect of the function setpgrp in AT&T-UNIX is also, that the controlling
terminal will be changed by this call.
Some processes, which will check the controlling terminal will fail (like pg).
On the other hand a logout by switching the terminal off will be ignored
(SIGHUP) by the whole process group.
