Hi

I've googled for this but didn't strike gold.

I'm working on a linux box but would welcome pointers to any
basic signal handling documentation online.

I have read the book "Using C on the Unix system" but it was
printed in 1991 so it's not up to date.

I accept that I may have to buy a book on this. (perhaps
Addison Wesley-Advanced Programming in the UNIX Environment)

Any recommendations for online docs? Or failing that, printed
material.

Thanks,
