int SDL_isalpha(int x);

🌸 DESCRIPTION 🌸

Okay so here's the tea, and it's important tea, so listen up. 🫖

⚠️ WARNING: no matter what your system locale is doing — literally regardless of it — this function will only treat ASCII values for English 'a-z' and 'A-Z' as true. That's it. That's the whole vibe. Don't come for it with your fancy locale expectations, it's not gonna happen. 💅

🎀 FUNCTION PARAMETERS 🎀

• x — the character value you wanna check. that's it, that's the whole input. 👑

💫 RETURN VALUE 💫

Returns non-zero if x falls within the character class, and zero otherwise. So like... truthy = yes it's a letter, falsy = nope bestie, not a letter. 🦋

🔥 THREAD SAFETY 🔥

It is safe to call this function from any thread. Go off, call it from literally wherever, it does not care. Main character energy, zero drama. 👑

🌈 AVAILABILITY 🌈

This function is available since SDL 3.2.0. So if you're on something older... girl. upgrade. 😭
