💖 explain_waitpid_or_die(3) 💖

okay bestie, so this is a page from the Library Functions Manual, and it's literally all about explain_waitpid_or_die — yes that's a whole mouthful, iykyk, but it's iconic, trust. 🫶

✨ NAME ✨

explain_waitpid_or_die — wait for process to change state and report errors 💅

---

🌸 SYNOPSIS 🌸

#include <libexplain/waitpid.h>
int pid = explain_waitpid_or_die(int pid, int *status, int options);

like, that's the whole vibe. short, sweet, slays.

🦋 DESCRIPTION 🦋

so the explain_waitpid_or_die function is used to call the waitpid(2) system call. no cap. and here's the tea — on failure, an explanation will be printed to stderr, obtained from explain_waitpid(3), and then the process terminates by calling exit(EXIT_FAILURE). 😭 it just ends it all, fr fr.

this function is intended to be used in a fashion similar to the following example:

explain_waitpid_or_die(pid, status, options);

now let's break down the arguments, because the way each one is exactly what you'd pass to the waitpid(2) system call is giving "no notes, no edits, just vibes": ✨

• pid — the pid, exactly as to be passed to the waitpid(2) system call. 💖
• status — the status, exactly as to be passed to the waitpid(2) system call. 💖
• options — the options, exactly as to be passed to the waitpid(2) system call. 💖

Returns:

this function only returns on success. on failure, it prints an explanation and exits. so like, if you got a return value back, congrats bestie, you ate. 👑
