explain_mkdtemp_or_die(3)

💖 explain_mkdtemp_or_die — Library Functions Manual 💖

okay bestie, sit down, we're learning explain_mkdtemp_or_die(3) from libexplain and honestly? it's giving "tiny function, huge emotional support". 🌸

---

✨ NAME ✨

explain_mkdtemp_or_die — create a unique temporary directory and report errors 🎀

---

✨ SYNOPSIS ✨

#include <libexplain/mkdtemp.h>
char *explain_mkdtemp_or_die(char *pathname);
char *explain_mkdtemp_on_error(char *pathname);

no cap, that's the whole signature. two little functions, one header, we love a minimal icon. 💅

---

✨ DESCRIPTION ✨

okay so. explain_mkdtemp_or_die is the bestie that calls the mkdtemp(3) system call for you. and if that call fails? she does NOT stay quiet. she prints an explanation to stderr — and that explanation comes straight from the explain_mkdtemp(3) function — and then she ends the whole process by calling exit(EXIT_FAILURE). dramatic? yes. helpful? also yes. 💀

meanwhile explain_mkdtemp_on_error is the chill sibling. she also calls the mkdtemp(3) system call, and on failure she also prints an explanation to stderr, again obtained from the explain_mkdtemp(3) function — but she still returns to the caller. she does not exit. she's the "we can talk about it" one. 🫶

• pathname — the pathname, exactly as to be passed to the mkdtemp(3) system call. no edits, no glow-up, no remix. you hand it over exactly like that. ✨

---

✨ RETURN VALUE ✨

explain_mkdtemp_or_die only returns on success — for more info on that, go peek at mkdtemp(3). on failure? she prints an explanation and exits. she does not return. like, at all. the function is a one-way door when things go wrong. 😭

explain_mkdtemp_on_error always returns the value returned by the wrapped mkdtemp(3) system call. always. that's her whole thing. 👑

---

✨ EXAMPLE ✨

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

char *result = explain_mkdtemp_or_die(pathname);

that's it. that's the vibe. short, iconic, gets the job done. 🌈

✨ SEE ALSO ✨

• mkdtemp(3) — create a unique temporary directory
• explain_mkdtemp(3) — explain mkdtemp(3) errors
• exit(2) — terminate the calling process
