exit signal

[DanKarron at UCBVAX.BERKELEY.EDU]

How can I set a signal handler for a software exit() call ? I am
looking to catch programs that exit via an exit(value) call, or fall
off the end of the main procedure. I do not have control of the user code.

I want to save the window state of the application program. I have
a macro to edit "exit(value)" to "Exit(value)", but that does not catch
mains falling off the end, or exit() with no args.

I tried SIGTERM, but that does not do what I want. What does it do ?

Cheers!

dan.
