This project is about Managing processes in C using UNIX signals.

Seems like it’s better to use sigaction instead of signal ( source). It’s behavior is more rigorously defined and it also can receive PID of a sender process (I think). It’s also more portable.

See also getpid().

It’s possible for a process to send signals to itself. Weird.
