💖 idn2_strerror(3) — the libidn2 girlies' guide 💖

okay bestie, so this is a page from libidn2, the library that does the internationalized domain name thing. and this particular function? it's the one that tells you why everything went wrong. she's the translator. the emotional support friend of error codes. 🫶

✨ NAME ✨

idn2_strerror — an API function, and honestly? a lifesaver.

🌸 SYNOPSIS 🌸

#include <idn2.h>

const char * idn2_strerror(int rc);

🎀 ARGUMENTS 🎀

  • int rc — the return code you got handed by some other libidn2 function. yeah. that one. bring it here and she'll explain what it meant. 🧚

👑 DESCRIPTION 👑

So basically: you take an internal libidn2 error code and this function converts it into a humanly readable string. no cap, that's the whole job. she takes the cryptic little number and turns it into words you can actually read with your eyeballs. 💅

⚠️ important bestie: the returned pointer must not be de-allocated by the caller. do NOT free() her. she does not belong to you. she is a guest. 🙈

Return value: a humanly readable string describing the error. that's it. that's the tea. ☕
