💖 explain_getchar_or_die — Library Functions Manual 💖

okay bestie, pull up a chair, we're doing explain_getchar_or_die(3) from the Library Functions Manual and it's honestly so iconic of it to exist 🫶

---

✨ NAME ✨

explain_getchar_or_die — input of characters and report errors 💅

---

🌸 SYNOPSIS 🌸

#include <libexplain/getchar.h>
void explain_getchar_or_die(void);

like. that's it. that's the whole entrance. no args, no drama, no cap 🎀

---

🦋 DESCRIPTION 🦋

so explain_getchar_or_die is that girl who calls the getchar(3) system call for you. but here's the thing — she's not gonna just quietly let it fail like some other functions 🙈

if it fails? she prints an explanation to stderr, and that explanation comes straight from explain_getchar(3). and then — and this is the part — she terminates the whole process by calling exit(EXIT_FAILURE). literally main character energy: either it works or we're all going home 😭

she's meant to be used in a vibe that looks a lot like this:

int c = explain_getchar_or_die();

💀 Returns:

• this function only returns on success
• on failure, it prints an explanation and exits. like, exits exits. that's the "or_die" part bestie, it's not a metaphor 🔥

⚠️ fr fr — if you're not ready for the process to be over, maybe don't invite her to the party.
