explain_endgrent_or_die(3)

✨ explain_endgrent_or_die(3) ✨

okay bestie, gather round 💖 this one is from the libexplain crew, and it's literally the explain_endgrent_or_die page. Yes that's a mouthful, we're gonna get through it together 🫶

---

🌸 NAME 🌸

explain_endgrent_or_die — finish group file accesses and report errors 💅

---

🎀 SYNOPSIS 🎀

#include <libexplain/endgrent.h>
void explain_endgrent_or_die(void);
void explain_endgrent_on_error(void);

like. two whole functions. no args. we love a low-maintenance icon 👑

---

🦋 DESCRIPTION 🦋

So explain_endgrent_or_die is the function you call to call the endgrent(3) system call. That's the whole vibe. It's a lil wrapper 🧚

But here's the tea ☕ — if it fails? An explanation gets printed to stderr, and that explanation comes from the explain_endgrent(3) function. And then the process just… terminates, by calling exit(EXIT_FAILURE). Not me ending the whole program 💀 but yes, that's literally what it does.

Then there's explain_endgrent_on_error, the softer sister 🌸 she also calls the endgrent(3) system call, and on failure she also prints an explanation to stderr (again, obtained from explain_endgrent(3)), but she still returns to the caller. no dramatic exits. she stays. she's loyal 🥹

---

💜 RETURN VALUE 💜

explain_endgrent_or_die only returns on success — check endgrent(3) for more deets on that. On failure? It prints an explanation and exits. It does not return. Like, at all. bye 👋

explain_endgrent_on_error always returns the value returned by the wrapped endgrent(3) system call. every time. no cap.

---

⭐ EXAMPLE ⭐

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

explain_endgrent_or_die();

that's it. that's the example. iconic behaviour honestly 👑
