WebFeb 6, 2024 · The child process uses SIGHUP instead of SIGIO (although a realtime signal, say SIGRTMIN+0, would be safer); if generated by the parent process exiting, the SIGHUP signal handler will raise SIGTERM in the child. To make the termination causes easy to see, the child catches SIGTERM, and exits the next iteration (a second later).
