Wait for and/or kill process grandchildren produced by fork

Question

I fork() into process X and Y, afterwards Y forks() again into itself and process Z multiple times.

Now process Y is some kind of \"listene

Answer 1

Your question does a terrific job of making the actual problem hard to understand. Still, I believe I can discern the following: "I want to get rid of the zombies". Well, don't we all.

There are multiple ways of doing this:

• Have Y ignore SIGCHLD. forked children will not turn into zombies when they die
• Have Y periodically reap (wait) for any children

It's your choice which one you use, but it seems to me the first is what you want.
