💖 NAME 💖

ok so bestie, meet explain_close_or_die — she closes a file descriptor and then reports errors like the icon she is 🎀

---

✨ SYNOPSIS ✨

#include <libexplain/close.h>
void explain_close_or_die(int fildes);

that's it. that's the whole vibe check 🦋

---

🌸 DESCRIPTION 🌸

okay so, the explain_close_or_die function is literally built to call the close(2) system call for you. and bestie, if things go wrong? on failure an explanation gets printed to stderr — that explanation is obtained from explain_close(3) — and then the process terminates by calling exit(EXIT_FAILURE). no takebacks, no second chances, she just ✨ leaves ✨ 💀

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

explain_close_or_die(fildes);

• fildes — the fildes, exactly as to be passed to the close(2) system call. like, character for character, don't get cute with it 💅

Returns:

• this function only returns on success. on failure, she prints an explanation and exits. periodt 👑

not me warning you: if it fails, you don't get to keep running. she's already gone. main character exit energy fr fr 😭
