SDL_HasAVX(3)

💖 SDL_HasAVX 💖

okay bestie, so this one lives in the SDL3 family of functions, and it's basically the "does ur CPU have the fancy AVX thing" detector ✨

---

🌸 NAME 🌸

SDL_HasAVX — figure out whether the CPU has AVX features, no cap 🔍

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_cpuinfo.h>

bool SDL_HasAVX(void);

like. that's the whole thing. one include, one function, zero arguments. she's low maintenance 💅

---

🎀 DESCRIPTION 🎀

so here's the tea: this function asks ur CPU if it's got AVX going on.

and the important bit, bestie — on CPUs that aren't using Intel instruction sets, this always returns false. always. no exceptions. so if ur rocking something non-Intel-instruction-set flavored, don't even get ur hopes up 🫶

---

🦋 RETURN VALUE 🦋

• true — yasss, the CPU has AVX features 👑
• false — nope, it does not 🙈

---

💜 THREAD SAFETY 💜

you can call this from any thread. literally any of them. go wild. no locks, no stress, it's giving thread-safe icon behavior ✨

---

🌈 AVAILABILITY 🌈

this function has been around since SDL 3.2.0, so if ur on anything older she's not invited to the party 😭

💀 tiny reminder: this is a detection function, not a "please turn on AVX" function. it just tells u what's already there. vibe check only, no buttons pressed 🎀
