Signal handling

Hi! I was actually wanted to refresh my knowledge on signal handling, is there a good tutorial, or a good book that i can find which would allow me to do this. I did signal handling in a OS class couple of years back, never used it so, i am rusty but just wanted to see how useful ,it can be in anything i might be doing from now on.

Thanks a lot.

Signal handling under which OS?

Under Linux take a look at:
man 3 signal
or
man 2 sigaction

If you are using Vc++ take a look at the:
Process and Environment Control
there you can find something about signal
