SDL_ThreadFunction(3type)

💖 SDL_ThreadFunction 💖

okay bestie, welcome to the SDL_ThreadFunction(3type) page — it's a datatype situation, part of the SDL3 datatypes era, and honestly? it's giving "tiny but crucial" 💅

---

✨ NAME ✨

SDL_ThreadFunction — the function you hand over to SDL_CreateThread() so it can be the entry point of your brand new thread. like, it's literally the first thing your baby thread does with its life 🦋

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_thread.h>

typedef int (SDLCALL *SDL_ThreadFunction) (void *data);

look at that signature. look at it. int return, void *data in, SDLCALL doing its little calling-convention moment. iconic, no notes 👑

---

🎀 FUNCTION PARAMETERS 🎀

• data — literally just whatever you passed as data to SDL_CreateThread(). that's it, that's the whole vibe. it comes back to you here, same as you sent it 💫

---

⭐ RETURN VALUE ⭐

you return a value, and that value can get reported back out through SDL_WaitThread(). so like… your return value isn't shouting into the void, it gets picked up later. main character energy fr fr 🙈

---

🌈 AVAILABILITY 🌈

this datatype has been available since SDL 3.2.0. so if you're on anything older, bestie, it's not here yet 😭

---

lowkey reminder: keep that signature exact. int, SDLCALL, void *data. don't get creative with it, the compiler will absolutely clock you 💀

mwah 💋 that's the whole page. written up by the lovely folks over at Simple Directmedia Layer, tagged SDL 3.4.18, and filed under SDL_ThreadFunction(3type) — go make some threads, you absolute icon 🫶✨
