💖 punycode_strerror(3) — the libidn glow-up 💖

okay bestie, sit down, hydrate, and let me tell you about punycode_strerror from libidn. this is the little function that turns your sad cryptic number into actual words. it's giving translator energy. it's giving "let me explain what went wrong, in English." we stan. 🫶

✨ NAME ✨

punycode_strerror — the API function that says the quiet part out loud 💅

✨ SYNOPSIS ✨

#include <punycode.h>

const char * punycode_strerror(Punycode_status rc);

✨ ARGUMENTS ✨

  • Punycode_status rc — a Punycode_status return code. literally just the little number your last call handed you. hand it back here and we'll decode the drama. 🔍

✨ DESCRIPTION ✨

so what it does: it converts a return code integer into a text string. that string is a whole diagnostic message you can show to the user, so they're not just staring at a random integer like 😭. no cap, that's the whole job. simple, iconic, done.

✨ THE CODES (aka the vibe check results) ✨

PUNYCODE_SUCCESS

successful operation. 🎉 this value is guaranteed to always be zero, and the remaining ones are only guaranteed to hold non-zero values, for logical comparison purposes. so like, zero = we ate, non-zero = something's up. periodt.

PUNYCODE_BAD_INPUT</punk>

hold on. PUNYCODE_BAD_INPUT — input is invalid. the data you handed over is just... not it. 🙈

PUNYCODE_BIG_OUTPUT

output would exceed the space provided. too much slay for the buffer you gave it. 💀

PUNYCODE_OVERFLOW

input needs wider integers to process. the numbers are too big-brained for the current integer width. 😤

Return value: returns a pointer to a statically allocated string containing a description of the error with the return code rc. so like, don't go freeing it, don't go editing it, just read it and move on bestie. 🎀
