Process Control

Hi,

Someone recently asked me the best way to control the number of
foreground and background processes a user can run on the system. I had
a prod around in a few places and pondered the concept of getting the
kernel to limit the max number of processes in login.conf, as sort of
sub-limits of maxproc.

The best way I could come up with doing this kernel-side is by watching
a process' P_CONTROLT flag when a process is created (or tries to fork).
If the process had the flag, I assumed it to be foreground, if not,
background.

If anyone has any other suggestions on how to distinguish fg/bg apart,
or on the concept in general, I'd appreciate some feedback!

Regards,


Alan
