💖 tld_get_4z — bestie's guide to pulling a TLD out of a string 💖

okay so this is tld_get_4z(3) from libidn, and if you're here it's because you have a pile of unicode code points and you need the top-level domain out of it. say less, i got you 🫶

✨ NAME ✨

tld_get_4z — it's an API function, and it's literally here to isolate your top-level domain 💅

🌸 SYNOPSIS 🌸

#include <tld.h>

int tld_get_4z(const uint32_t * in, char ** out);

🎀 ARGUMENTS 🎀

  • const uint32_t * in — a zero terminated array of unicode code points to process. yeah, the whole uint32_t situation, that's the input, that's her ✨
  • char ** out — a zero terminated ascii result string pointer. this is where the glow-up lands 💖

🦋 DESCRIPTION 🦋

so what this does: it isolates the top-level domain of in and returns it as an ASCII string in out. that's it. that's the whole vibe. 🌈

Return value: it returns TLD_SUCCESS on success, or the corresponding Tld_rc error code otherwise. so like, if it's not TLD_SUCCESS, go read your Tld_rc and figure out what happened, bestie 😭

ngl, always check the return value. TLD_SUCCESS is the slay, everything else is a vibe check you gotta take seriously 🔥
