explain_mkostemp_or_die(3)

✨ NAME ✨

okay so bestie, welcome to explain_mkostemp_or_die(3) — the libexplain page that lives in the Library Functions Manual 💖 — and it's literally just: create a unique temporary file and report errors. that's the whole vibe. mkostemp but it tells you what went wrong instead of leaving you guessing. iconic behavior honestly 🎀

---

🦋 SYNOPSIS 🦋

#include <libexplain/mkostemp.h>
int explain_mkostemp_or_die(char *templat, int flags);
int explain_mkostemp_on_error(char *templat, int flags);

two functions, one header, no cap ✨

💅 DESCRIPTION 💅

so here's the tea, bestie 🍓

The explain_mkostemp_or_die function is used to call the mkostemp(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_mkostemp(3) function, and then the process terminates by calling exit(EXIT_FAILURE). like… it does NOT come back. it's giving dramatic exit, and honestly? valid 💀

The explain_mkostemp_on_error function is used to call the mkostemp(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_mkostemp(3) function, but still returns to the caller. so this one's the chill sibling — it tells you what's wrong and then just… hands you back the keys 🫶

• templat — the template, exactly as to be passed to the mkostemp(3) system call. no edits, no little tweaks, exactly as-is, periodt 👑
• flags — the flags, exactly as to be passed to the mkostemp(3) system call. same energy. hand them over exactly how they are ✨

---

👑 RETURN VALUE 👑

The explain_mkostemp_or_die function only returns on success, see mkostemp(3) for more information. On failure, prints an explanation and exits, it does not return. like, at ALL. the door is closed. it's gone. no cap 🚪💨

The explain_mkostemp_on_error function always returns the value return by the wrapped mkostemp(3) system call. so whatever mkostemp(3) gave back, you get back. simple as that 💜

---

🌈 EXAMPLE 🌈

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

int result = explain_mkostemp_or_die(templat, flags);

look at her. one line. main character energy fr fr ⭐
