[net.unix-wizards] Question About Group Process IDs

radio@spuxll.UUCP (Rick Farina) (11/13/85)

I understand that if one detaches a process from the rest of its
process group via setpgrp(2), then there is no way (i.e. no section 2
or 3 functions) to subsequently reattach to the original process group. 

Does anybody know why this is so?

Thanx in advance.
