SDL_iOSAnimationCallback(3type)

💖 SDL_iOSAnimationCallback 💖

okay bestie, so this is a page from the SDL3 DATATYPES corner of the SDL3 manual, section 3type, and it's all about one lil' function-pointer type. it's giving "tiny but important", fr fr. 🎀

---

✨ NAME ✨

SDL_iOSAnimationCallback — the prototype for an Apple iOS animation callback. yes that's the whole vibe, she's a typedef and she knows it 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_system.h>

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

like, look at her. void return, one void *userdata parameter, SDLCALL calling convention. iconic. no cap. ✨

---

🦋 DESCRIPTION 🦋

okay so this datatype is only useful on Apple iOS — that's the whole audience, bestie. if you're not on iOS, this is not your moment. 🙈

but here's the tea: once you pass a function pointer of this type into SDL_SetiOSAnimationCallback, the system will call that function pointer at a regular interval. that's it, that's the deal. it just keeps showing up, like a good friend who texts you every day. 🫶

---

🎀 FUNCTION PARAMETERS 🎀

• userdata — this is literally whatever you passed in as callbackParam to SDL_SetiOSAnimationCallback. it comes back to you as callbackParam... wait, no, it comes back as userdata. it's the same thing, it just changed its name for the function-pointer era. main character energy, honestly. 😭

---

⭐ AVAILABILITY ⭐

this datatype has been available since SDL 3.2.0. so if you're on something older... bestie, upgrade. 🧚

---

lowkey reminder: the callback type alone does nothing. it only starts vibing at a regular interval after you hand it to SDL_SetiOSAnimationCallback. so don't just declare one and expect magic, okay? 🍓

and that's the page! brought to you by Simple Directmedia Layer, SDL version SDL 3.4.18, in the SDL_iOSAnimationCallback(3type) era. mwah, love u, go write some callbacks 💖✨🎀🦋🌸💅🫶
