✨ idn2_strerror_name ✨

okay bestie, so this is a page from libidn2 (the idn2_strerror_name(3) one, section 3, we love a library function moment 💅). she's a tiny little helper and honestly? iconic. let's get into it 🦋

🌸 NAME 🌸

idn2_strerror_name — it's an API function, that's the whole vibe 🎀

✨ SYNOPSIS ✨

#include <idn2.h>

const char * idn2_strerror_name(int rc);

look at her. so small. so powerful. 💖

🧚 ARGUMENTS 🧚

  • int rc — a return code that came from some other libidn2 function. like, you got a code back from somewhere and now you're bringing it here to get answers. 🫶

💜 DESCRIPTION 💜

so basically, this function takes an internal libidn2 error code and converts it into a string that matches the internal header file symbols. like it's translating error-code brain into symbol-name language. no cap. 😌

for example:

idn2_strerror_name(IDN2_MALLOC)

will return the string:

"IDN2_MALLOC"

and that's it, that's the whole trick. it's giving translator. it's giving bilingual but for error codes. 🌈

bestie, LISTEN — the caller must not try to de-allocate the returned string. do NOT free() her. do NOT free() her. she is not yours to free. 🙈 leave the returned string alone, it's not your business to manage, okay?? 😭

Return value: a string corresponding to the error code symbol. 🎀
