import DearImGui.Impl.SDL3 qualified as ImplSDL3
import Foreign.Marshal.Alloc (alloca)
import Foreign.Ptr (Ptr)
import SDL3.Sys qualified as SDL3

forEachEvent :: (Ptr SDL3.SDL_Event -> IO ()) -> IO ()
forEachEvent handle = alloca \event -> fix \next -> do
  pending <- ImplSDL3.pollEvent event
  when pending do
    handle event
    next
