In some of the programs and (csh) scripts that I write, I would like to take
different action depending on whether the program or script is exectuing in
the foreground or background.

I was wondering if any of you could provide a (hopefully) simple answer
to the following question:

    Is there anyway a C program can determine if it is being executed in
    the foreground vs. background (via **env or some other mechanism)?

    Is there a similar mechanism for C-shell (csh) scripts?

Any help would be greatly appreciated.

Thanks in advance,

Larry Ader
