explain_freopen_or_die(3)

💖 explain_freopen_or_die — from the libexplain manual, bestie 💖

okay so this one lives in the Library Functions Manual, and it's called explain_freopen_or_die(3). yes the name is a whole mouthful, we love her anyway 🫶

✨ NAME ✨

explain_freopen_or_die — open file and report errors 👑

---

🌸 SYNOPSIS 🌸

#include <libexplain/freopen.h>
void explain_freopen_or_die(const char *pathname, const char *flags,
       FILE *fp);

---

🦋 DESCRIPTION 🦋

so the explain_freopen_or_die function is what you call when you wanna reopen a file via the freopen(3) system call. and listen — if it fails, it does not just quietly ghost you. nope. it prints an explanation, which it gets from the linexplain_freopen(3) function, straight onto the standard error stream, and then it exits. dramatic? maybe. necessary? absolutely. 💅

this function is meant to be used in a fashion similar to this lil example right here:

explain_freopen_or_die(pathname, flags, fp);

and now the arg breakdown, one by one, no skips:

• pathname — the pathname, exactly as to be passed to the freopen(3) system call. like, don't get cute with it, pass it exactly. 🎀
• flags — the flags, exactly as to be passed to the freopen(3) system call. same energy, exactly as-is. ✨
• fp — the fp, exactly as to be passed to the freopen(3) system call. yes, exactly. all three of them, exactly. 😭

Returns:

• only ever return on success. never returns on failure. that's it, that's the whole deal — on failure she's gone, no return, periodt. 💀
