explain_mkstemp_or_die(3)

✨ explain_mkstemp_or_die(3) ✨

okay bestie, welcome to the Library Functions Manual section of the group chat 💅 this one's from libexplain and it's giving "make a temp file and don't be dramatic about it." let's get into it 🫶

---

🌸 NAME 🌸

explain_mkstemp_or_die — create a unique temporary file and report errors ✨

---

🎀 SYNOPSIS 🎀

#include <libexplain/mkstemp.h>
int explain_mkstemp_or_die(char *templat);
int explain_mkstemp_on_error(char *templat);

like, two lil functions, one header, we're so back 🦋

---

💖 DESCRIPTION 💖

So here's the vibe. explain_mkstemp_or_die is literally just here to call the mkstemp(3) system call for you. iconic behavior. and if it fails?? an explanation gets printed to stderr — that explanation comes straight from the explain_mkstemp(3) function, no cap — and then the process terminates by calling exit(EXIT_FAILURE). like, it's done. it does not come back. periodt 💀

Then we have explain_mkstemp_on_error, which also calls the mkstemp(3) system call. On failure it still prints that explanation to stderr (again, from explain_mkstemp(3)), but it still returns to the caller. so you get the drama of the error message without the whole "process is dead now" situation. soft launch energy 🌈

templat — the template, exactly as to be passed to the mkstemp(3) system call. exactly. as-is. don't get cute with it 🙈

---

⭐ RETURN VALUE ⭐

explain_mkstemp_or_die only returns on success, so peek at mkstemp(3) for more info on that. On failure? it prints an explanation and exits — it does not return. at all. bye 👑

explain_mkstemp_on_error always returns the value return by the wrapped mkstemp(3) system call. (yes, "return by", that's the original wording, we're keeping it, it's a vibe 😭)

---

🦋 EXAMPLE 🦋

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

int result = explain_mkstemp_or_die(templat);

and that's it. one line. main character energy fr fr ✨
