💖 explain_tmpnam_or_die — Library Functions Manual ✨

okay bestie, welcome to explain_tmpnam_or_die(3), she's giving temporary file name generator with a built-in therapist. iykyk 💅

🌸 NAME 🌸

explain_tmpnam_or_die — create a name for a temporary file and report errors. literally that's the whole gig, no cap 🎀

---

✨ SYNOPSIS ✨

#include <libexplain/tmpnam.h>
char *explain_tmpnam_or_die(char *pathname);
char *explain_tmpnam_on_error(char *pathname);

two functions, one header, zero drama (well, some drama, but the intentional kind 🫶)

---

🦋 DESCRIPTION 🦋

so here's the tea ☕

The explain_tmpnam_or_die function is used to call the tmpnam(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tmpnam(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

bestie. she does NOT come back if things go wrong. she prints the whole explanation to stderr, courtesy of explain_tmpnam(3), and then she calls exit(EXIT_FAILURE) and dips. periodt. 💀

The explain_tmpnam_on_error function is used to call the tmpnam(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tmpnam(3) function, but still returns to the caller.

this one is the chill sister 🌈 she still prints that explanation to stderr (same explain_tmpnam(3) hookup), but she comes back. she returns to you. she's not abandoning you. main character energy tbh.

🍓 pathname 🍓

• The pathname, exactly as to be passed to the tmpnam(3) system call.

like, don't get cute with it, don't tweak it, don't "improve" it — hand it over exactly as tmpnam(3) expects it. ✨

---

👑 RETURN VALUE 👑

The explain_tmpnam_or_die function only returns on success — see tmpnam(3) for more information. On failure, prints an explanation and exits, it does not return.

so like... if she returns, congrats, it worked 🎉 if she doesn't return, that's not a mystery, that's a rage quit into exit(EXIT_FAILURE). 😭

The explain_tmpnam_on_error function always returns the value return by the wrapped tmpnam(3) system call.

always. returns. the. value. she's reliable like that 💜

---

🌈 EXAMPLE 🌈

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

char *result = explain_tmpnam_or_die(pathname);

one line, iconic, ate 🎀
