Thank you for pointing out! I implemented ‘SDL_main_impl.h’ in version 0.8.1b0, you can now use callbacks like this:

os.environ["SDL_MAIN_USE_CALLBACKS"] = "1"

import sdl3

@sdl3.SDL_AppInit_func
def SDL_AppInit(appstate: sdl3.LP_c_void_p, argc: ctypes.c_int, argv: sdl3.LP_c_char_p) -> sdl3.SDL_AppResult: ...

@sdl3.SDL_AppIterate_func
def SDL_AppIterate(appstate: ctypes.c_void_p) -> sdl3.SDL_AppResult: ...

@sdl3.SDL_AppEvent_func
def SDL_AppEvent(appstate: ctypes.c_void_p, event: sdl3.LP_SDL_Event) -> sdl3.SDL_AppResult: ...

@sdl3.SDL_AppQuit_func
def SDL_AppQuit(appstate: ctypes.c_void_p, result: sdl3.SDL_AppResult) -> None: ...
