SDL_isxdigit — report if a character is a hexadecimal digit 💅

✨ SYNOPSIS ✨

#include <SDL3/SDL_stdinc.h>

int SDL_isxdigit(int x);

🌸 DESCRIPTION 🌸

WARNING: regardless of whatever the system locale is doing, this function will only treat ASCII values 'A' through 'F', 'a' through 'f', and '0' through '9', as true. that's it. that's the whole guest list. 🚫🌍

so like, don't come in here expecting locale-aware behaviour, because she does not know her. strictly ASCII, strictly those ranges, periodt. 🫶
