okay bestie, welcome to the <pink>explain_tempnam_or_die(3)</pink> page, she's a lil library functions manual girly and she is SO helpful 🫶

✨ NAME ✨

explain_tempnam_or_die — create a name for a temporary file and report errors 💅

---

🌸 SYNOPSIS 🌸

#include <libexplain/tempnam.h>
char *explain_tempnam_or_die(const char *dir, const char *prefix);
char *explain_tempnam_on_error(const char *dir, const char *prefix);

🦋 DESCRIPTION 🦋

so basically, <cyan>explain_tempnam_or_die</cyan> is the function you call when you wanna call the <cyan>tempnam(3)</cyan> system call. and like, if it fails? it prints an explanation to <yellow>stderr</yellow>, which it gets from the <cyan>explain_tempnam(3)</cyan> function, and then the process literally terminates by calling <cyan>exit(EXIT_FAILURE)` 💀 no coming back from that one, periodt.

and then there's <cyan>explain_tempnam_on_error</cyan> — same deal, she also calls the tempnam(3)system call. on failure she also prints an explanation tostderr(again, obtained fromexplain_tempnam(3)`), but she still returns to the caller. she's the chill one. 🧚

• dir — the dir, exactly as to be passed to the <cyan>tempnam(3)</cyan> system call. no editing, no vibes-based tweaking, pass it exactly ✨
• prefix — the prefix, exactly as to be passed to the <cyan>tempnam(3)</cyan> system call. same energy, exact copy, no cap 🎀

---

👑 RETURN VALUE 👑

<cyan>explain_tempnam_or_die</cyan> only returns on success — and if you wanna know more, go read <cyan>tempnam(3)` bestie. on failure she prints an explanation and exits, she does NOT return. like at all. bye 👋

<cyan>explain_tempnam_on_error</cyan> always returns the value return by the wrapped <cyan>tempnam(3)</cyan> system call. (yes, "return by", that's what it says, we're keeping it fr fr 🙈)

---

🌈 EXAMPLE 🌈

the <cyan>explain_tempnam_or_die</cyan> function is intended to be used in a fashion similar to the following example:

char *result = explain_tempnam_or_die(dir, prefix);
