Hi, I'm not sure if there's a posix way of doing this, but wanted to check
if there is a way in linux.
I want to have a daemon that fork/execs a new process, but don't want (for
various reasons) the responsibility for cleaning up those process with the
wait() function family. I'm assuming that if the init process became the
parent of one of these forked processes, then it would clean them up for me
(is this assumption true?). Besides the daemon process exiting, is there a
way to disown the process on purpose so that init inherits it?
Thanks,
Davy
Sounds like a job for the Richard Stevens "Advanced Programming in the
UNIX Environment" book. Check out chapter 13, "daemon processes". It
explains the subtleties of process groups, signals, inheritance, etc..
better than most.
