Is there a way to get the exit status of a child process created by fork() system call without the parent process pausing/waiting for its execution?

Specifically I need to print out the status of the exited process after it's done, but with the parent process continuing to do its thing in the meantime.

Still a beginner here; so as far as I know, you can't do that without using wait() and then testing it with the macros.

See duplicate: what you want is to use the parameter `WNOHANG` with `waitpid` function. – Mathieu Jan 10 '20 at 08:35

`SIGCHLD` might help you. But you still need some `wait` for getting the exit status. – dragosht Jan 10 '20 at 08:42
