SDL_AndroidGetExternalStorageState() takes the state as an output parameter and returns 0 if the function succeeds or a negative error code if there was an error.

The structures in this file are versioned separately from the rest of SDL, allowing better backwards compatibility and limited forwards compatibility with your application. Instead of calling `SDL_VERSION(&info.version)` before calling SDL_GetWindowWMInfo(), you pass the version in explicitly as SDL_SYSWM_CURRENT_VERSION so SDL knows what fields you expect to be filled out.
This header has been removed.
The Windows and X11 events are now available via callbacks which you can set with SDL_SetWindowsMessageHook() and SDL_SetX11EventHook().
The information previously available in SDL_GetWindowWMInfo() is now available as window properties, e.g.
```c
HWND hwnd = NULL;
SDL_SysWMinfo info;
SDL_VERSION(&info);
if (SDL_GetWindowWMInfo(window, &info) && info.subsystem == SDL_SYSWM_WINDOWS) {
hwnd = info.info.win.window;
}
if (hwnd) {
...
}
```
becomes:
```c
HWND hwnd = (HWND)SDL_GetProperty(SDL_GetWindowProperties(window), "SDL.window.win32.hwnd");
if (hwnd) {
...
}
```
