💖 SDL_MainThreadCallback 💖

okay bestie, so this is a page from the SDL3 DATATYPES manual, and it's about one very specific little guy: SDL_MainThreadCallback. it's giving "tiny type, big job" energy, and honestly? we're obsessed. 🫶

✨ NAME ✨

SDL_MainThreadCallback — the callback that runs on the main thread. that's it, that's the whole vibe. 💅

✨ SYNOPSIS ✨

#include <SDL3/SDL_init.h>

typedef void (SDLCALL *SDL_MainThreadCallback)(void *userdata);

look at her. a function pointer typedef. iconic. she returns void and takes exactly one void *. no notes. 🌸

✨ FUNCTION PARAMETERS ✨

  • userdata — an app-controlled pointer that gets passed straight to the callback. literally whatever you want it to be, bestie, it's your pointer, your rules. 🎀

✨ AVAILABILITY ✨

this datatype has been around since SDL 3.2.0. so if you're on something older than that... no she's not there yet, sorry babes. 😭

✨ SEE ALSO ✨

fr fr, the one rule of this callback: it runs on the main thread. that's the whole point. don't come for her, she's doing exactly what she said she'd do. 👑

and that's the tea, bestie!! 💜 this page came to you from the Simple Directmedia Layer girlies, living in SDL 3.4.18, filed under SDL_MainThreadCallback(3type). mwah, go slay your threading. 💖✨🦋
