• Signal 11 Caught In Process/fiber (unicorn Admin Handler)/(null) Email

I'm trying to solve the same problem, and since my program must run on OS X, the Linux-only solution didn't work for me.I came to the same conclusion as the other people on this page - there isn't a POSIX-compatible way of notifying a child when a parent dies. So I kludged up the next-best thing - having the child poll.When a parent process dies (for any reason) the child's parent process becomes process 1. If the child simply polls periodically, it can check if its parent is 1. If it is, the child should exit.This isn't great, but it works, and it's easier than the TCP socket/lockfile polling solutions suggested elsewhere on this page.

I don't believe it's possible to guarantee that using only standard POSIX calls. Like real life, once a child is spawned, it has a life of its own.It is possible for the parent process to catch most possible termination events, and attempt to kill the child process at that point, but there's always some that can't be caught.For example, no process can catch a SIGKILL. When the kernel handles this signal it will kill the specified process with no notification to that process whatsoever.To extend the analogy - the only other standard way of doing it is for the child to commit suicide when it finds that it no longer has a parent.There is a Linux-only way of doing it with prctl(2) - see other answers.
