💖 SDL_HasMMX 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, where we're checking in on SDL_HasMMX 🦋

---

✨ NAME ✨

SDL_HasMMX — determine whether the CPU has MMX features 💅

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_cpuinfo.h>

bool SDL_HasMMX(void);

---

✨ DESCRIPTION ✨

so basically this one goes and asks the universe "hey, does this CPU have MMX features?" 👑

and here's the tea: on CPUs that aren't using Intel instruction sets, this thing always returns false. like, always always. no cap. 🙈

---

✨ RETURN VALUE ✨

• returns true if the CPU has MMX features 🔥
• returns false if not 💀

---

✨ THREAD SAFETY ✨

it is safe to call this function from any thread 🫶 go wild, no locks needed, she's chill like that ✨

---

✨ AVAILABILITY ✨

this function is available since SDL 3.2.0 ⭐

---

🌸 quick vibe check: this is a yes/no question about your CPU, not a magic switch. you can't turn MMX on with it, you can only find out if it's already there. iykyk 💅
