explain_fstat_or_die(3)

💖 explain_fstat_or_die — Library Functions Manual 💖

okay bestie, sit down, hydrate, and let me tell you about explain_fstat_or_die(3) — she's a tiny little wrapper with main character energy and she will absolutely end your whole program if things go sideways. no cap. 🎀

---

✨ NAME ✨

explain_fstat_or_die — get file status and report errors 💅

---

🌸 SYNOPSIS 🌸

#include <libexplain/fstat.h>
void explain_fstat_or_die(int fildes, struct stat *buf);

like, that's the whole vibe. two args, no return value, pure chaos potential 🦋

🫶 DESCRIPTION 🫶

so the explain_fstat_or_die function is basically the chill way to call the fstat(2) system call. it does the thing, and if the thing fails? 😭 it prints an explanation to stderr — and that explanation comes straight from explain_fstat(3), which is the friend who always knows what went wrong — and then it terminates the process by calling exit(EXIT_FAILURE). dramatic? yes. necessary? also yes.

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

explain_fstat_or_die(fildes, buf);

and now the cast of characters, because every icon deserves an intro:

• fildes — the fildes, exactly as to be passed to the fstat(2) system call. no edits, no remixes, pass it as-is periodt.
• buf — the buf, exactly as to be passed to the fstat(2) system call. same energy. just hand it over. 🍓

Returns:

• This function only returns on success. On failure, prints an explanation and exits. that's it, that's the deal. it's giving "we ball or we leave" 💀
