EXPLAIN_SETLINEBUF_OR_DIE(3)

✨ explain_setlinebuf_or_die(3) ✨

okay bestie, welcome to the Library Functions Manual 💖 this one's all about explain_setlinebuf_or_die and its slightly-chiller sibling, and honestly? it's giving "wrap a thing, catch the errors, look cute doing it." let's get into it 🫶

---

🌸 NAME 🌸

explain_setlinebuf_or_die — stream buffering operations and report errors ✨

---

🎀 SYNOPSIS 🎀

#include <libexplain/setlinebuf.h>
void explain_setlinebuf_or_die(FILE *fp);
void explain_setlinebuf_on_error(FILE *fp);

like. two functions. one header. we love a tidy lil interface 💅

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕

The explain_setlinebuf_or_die function is used to call the setlinebuf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_setlinebuf(3) function, and then the process terminates by calling exit(EXIT_FAILURE). so like — it goes hard, no survivors, periodt 💀

The explain_setlinebuf_on_error function is used to call the setlinebuf(3) system call too. On failure an explanation will be printed to stderr, obtained from the explain_setlinebuf(3) function, but still returns to the caller. so this one's the emotionally mature sibling that doesn't just yeet the whole process 🧚

💜 the argument, bestie

• fp — The fp, exactly as to be passed to the setlinebuf(3) system call. no notes, no remixing, you hand it over exactly as-is, iykyk 👑

---

🌈 RETURN VALUE 🌈

The explain_setlinebuf_or_die function only returns on success — see setlinebuf(3) for more info, bestie. On failure, it prints an explanation and exits. it does not return. like, at all. it's gone. 🫡

The explain_setlinebuf_on_error function always returns the value return by the wrapped setlinebuf(3) system call. always. no drama, no exit, just hands you the value back 💖

---

⭐ EXAMPLE ⭐

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

explain_setlinebuf_or_die(fp);

that's it. that's the whole vibe. one line and you're done ✨
