explain_fopen_or_die(3)

💖 explain_fopen_or_die(3) 💖

okay so bestie, welcome to libexplain's explain_fopen_or_die(3) — it lives in the Library Functions Manual and it is literally here to open your file and be dramatic about it if anything goes wrong. no cap.

---

✨ NAME ✨

explain_fopen_or_die — open file and report errors 🫶

---

✨ SYNOPSIS ✨

#include <libexplain/fopen.h>

FILE *explain_fopen_or_die(const char *pathname, const char *flags);

like. look at her. two args, one FILE *, zero chill. 💅

---

🌸 DESCRIPTION 🌸

so the explain_fopen_or_die() function opens the file whose name is the string pointed to by pathname and associates a stream with it. that's the whole vibe. if you want the deep lore on that part, go read fopen(3), she's the icon.

this is a quick and simple way for programs to consistently report file open errors in a consistent and detailed fashion. ✨ yes queen, consistency twice, because that's the entire point. your errors show up detailed, your errors show up the same way every time, and you don't have to write any of it yourself.

---

🦋 RETURN VALUE 🦋

if everything slays: upon successful completion, explain_fopen_or_die returns a FILE pointer. 🎀

if it does not slay: if an error occurs, explain_fopen will be called to explain the error, which will be printed onto stderr, and then the process will terminate by calling exit(EXIT_FAILURE).

⚠️ okay so that "or_die" in the name is not a joke, bestie. an error means your process is gone. exit(EXIT_FAILURE), no survivors, no return, no take-backs. 💀
