SDL_iOSSetAnimationCallback

Use this function to set the animation callback on Apple iOS.

Header File

Defined in SDL_system.h, but apps should use #include <SDL3/SDL.h>

int SDL_iOSSetAnimationCallback(SDL_Window * window, int interval, void (SDLCALL *callback)(void*), void *callbackParam);

window	the window for which the animation callback should be set
interval	the number of frames after which callback will be called
callback	the function to call for every frame.
callbackParam	a pointer that is passed to `callback`.

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

The function prototype for callback is:

void callback(void* callbackParam);

Where its parameter, callbackParam, is what was passed as callbackParam to SDL_iOSSetAnimationCallback().

This function is only available on Apple iOS.

For more information see:

Note that if you use the "main callbacks" instead of a standard C main function, you don't have to use this API, as SDL will manage this for you.

Details on main callbacks are here:

This function is available since SDL 3.0.0.
