al_ustr_find_cset(3alleg5)

✨ NAME ✨

al_ustr_find_cset — bestie, it's part of the Allegro 5 API 💅

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

int al_ustr_find_cset(const ALLEGRO_USTR *us, int start_pos,
   const ALLEGRO_USTR *reject);

---

🦋 DESCRIPTION 🦋

okay so picture this: you've got this string us, right? And you're like, "bestie, where's the first code point that is NOT on my little reject list?" That's literally what this function does 💖

It hunts through us, starting from the byte offset start_pos, and finds the very first code point that does not match any code point in reject. In other words — and this is the iconic part — it finds a code point in the complementary set of reject ✨

And what does it give you back? The byte position of that code point, if there even is one. If there isn't? It hits you with a -1. no cap 😭
