💖 idn2_to_unicode_44i — the libidn2 glow-up page ✨

okay bestie, gather round, because we're talking about idn2_to_unicode_44i(3) from libidn2 and it's literally the "turn my ACE label back into its cute internationalized self" function. no cap. 🦋

✨ SYNOPSIS ✨

#include <idn2.h>

int idn2_to_unicode_44i(const uint32_t * in, size_t inlen, uint32_t *
out, size_t * outlen, int flags);

like, that's the whole vibe. five args, one return value, zero drama. 💅

🎀 ARGUMENTS 🎀

  • const uint32_t * in — bestie this is your input array, and it's full of UTF-32 code points. that's the raw material. ✨
  • size_t inlen — how many code points are actually in that input array. the headcount. the guest list. 💖
  • uint32_t * out — the output array, also UTF-32 code points. this is where the glow-up lands. 🌸
  • size_t * outlen — okay so this one is doing double duty and honestly? icon behaviour. on input it's the maximum size of the output array (in UTF-32 code points), and on exit it's the actual size of the output array (in UTF-32 code points). she goes in as a limit and comes out as a receipt. 🫶
  • int flags — currently unused. yes, really. it's just sitting there, main character energy, doing absolutely nothing. 🙈

💅 DESCRIPTION 💅

The ToUnicode operation takes a sequence of UTF-32 code points that make up one domain label and returns a sequence of UTF-32 code points. one label in, one label out. very demure, very mindful.

and here's the tea ☕ — if the input sequence is a label in ACE form, then the result is an equivalent internationalized label that is not in ACE form. it's giving "de-code me, un-punycode me, let me be my true self." ✨

otherwise? the original sequence is returned unaltered. untouched. left exactly as it was. she said "no notes." 💅

oh and ps — output may be NULL to test lookup of input without allocating memory. that's the pro move right there, no allocation, just vibes and a vibe check. 🧚

⭐ SINCE ⭐

2.0.0 — an elder, but make it iconic. 👑
