explain_tmpfile_or_die(3)

💖 explain_tmpfile_or_die(3) 💖

okay bestie, welcome to the Library Functions Manual entry for explain_tmpfile_or_die, and trust, this one is short but it eats. 🎀

---

✨ NAME ✨

explain_tmpfile_or_die — create a temporary file and report errors 🦋

---

🌸 SYNOPSIS 🌸

#include <libexplain/tmpfile.h>
FILE *explain_tmpfile_or_die(void);
FILE *explain_tmpfile_on_error(void);

---

💅 DESCRIPTION 💅

So the explain_tmpfile_or_die function is the one you call when you want to call the tmpfile(3) system call, but you want the ✨drama✨. On failure, an explanation gets printed to stderr — and that explanation is obtained from the explain_tmpfile(3) function — and then the process terminates by calling exit(EXIT_FAILURE). it's giving "we die with receipts". 💀

The explain_tmpfile_on_error function is the calmer sibling. It also calls the tmpfile(3) system call, and on failure an explanation is printed to stderr, again obtained from the explain_tmpfile(3) function — but this one still returns to the caller. no exit, no chaos, just vibes and information. 🫶

---

⭐ RETURN VALUE ⭐

The explain_tmpfile_or_die function only returns on success, and you can peek at tmpfile(3) for more info on that. On failure, it prints an explanation and exits — so lowkey it does not return. periodt. 👑

The explain_tmpfile_on_error function always returns the value return by the wrapped tmpfile(3) system call. 🧚

---

🌈 EXAMPLE 🌈

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

FILE *result = explain_tmpfile_or_die();

like yes, that's the whole thing, iconic behavior honestly. 🔥
