explain_fpurge_or_die(3)

💖 explain_fpurge_or_die — Library Functions Manual 💖

okay bestie, sit down, hydrate, and let me tell you about explain_fpurge_or_die(3) from the libexplain library functions crew. this one is a lil glow-up wrapper situation and honestly? it's giving "I handle your errors so you don't have to" energy. 🎀

✨ NAME ✨

explain_fpurge_or_die — purge a stream and report errors. that's it, that's the whole job, and she does it flawlessly. 💅

---

🦋 SYNOPSIS 🦋

#include <libexplain/fpurge.h>
void explain_fpurge_or_die(FILE *fp);
int explain_fpurge_on_error(FILE *fp);

---

🌸 DESCRIPTION 🌸

so there's these two functions and they're basically sisters, right? one is the dramatic one and one is the chill one.

The explain_fpurge_or_die function is used to call the fpurge(3) system call. and the way that it's built? if things go wrong, an explanation gets printed to stderr, and that explanation is obtained from the explain_fpurge(3) function. then — and this is the "or die" part, no cap — the process terminates by calling exit(EXIT_FAILURE). it really said "if I'm going down, I'm taking the whole program with me." 💀

The explain_fpurge_on_error function is used to call the fpurge(3) system call too. on failure an explanation will be printed to stderr, obtained from the explain_fpurge(3) function, but this one still returns to the caller. she's the emotionally stable sister. she tells you what went wrong and then just... lets you keep living your life. 🫶

• fp — the fp, exactly as to be passed to the fpurge(3) system call. like, don't get creative with it, pass it through as-is, periodt.

---

👑 RETURN VALUE 👑

The explain_fpurge_or_die function only returns on success — see fpurge(3) for more information. on failure? it prints an explanation and exits. it does not return. it's gone. it left the chat. 😭

The explain_fpurge_on_error function always returns the value return by the wrapped fpurge(3) system call. every single time, she hands you the receipt. 🧾

---

🌈 EXAMPLE 🌈

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

explain_fpurge_or_die(fp);

iconic. one line. ate. ✨
