explain_closedir_or_die(3)

💖 explain_closedir_or_die — Library Functions Manual 💖

okay bestie, gather round, we're doing a manual page and it's literally about the tiniest little function ever. it's explain_closedir_or_die(3) and no, the name is not a threat, it's a lifestyle. 🎀

✨ NAME ✨

explain_closedir_or_die — close a directory and report errors 🫶

---

🌸 SYNOPSIS 🌸

#include <libexplain/closedir.h>
void explain_closedir_or_die(DIR *dir);

that's it. that's the whole vibe. one include, one call, zero regrets. ✨

🦋 DESCRIPTION 🦋

so like, the explain_closedir_or_die function is what you call when you wanna call the closedir(3) system call, but you're emotionally prepared for it to go wrong. 💅

here's the tea: on failure, an explanation gets printed to stderr, and that explanation is obtained from explain_closedir(3). then — and this is the dramatic part — the process terminates by calling exit(EXIT_FAILURE). no second chances, no "let me think about it", it's just done. main character exit. 💀

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

explain_closedir_or_die(dir);

like, that's it. that's the whole call. slay.

• dir — the dir, exactly as to be passed to the closedir(3) system call. exactly. as in, don't get cute with it, pass it the way closedir(3) wants it. 🍓

Returns:

• this function only returns on success. on failure, it prints an explanation and exits. so if you get a return value back at all, congrats, it worked, that's the good timeline. 🌈

ngl bestie, if you see this function return, you're winning. if you don't see it return, well. it's giving exit(EXIT_FAILURE). 🙈
