int* w,
int* h)

Remarks
This may differ from SDL_GetWindowSize() if we're rendering to a high-DPI drawable, i.e. the window was created with SDL_WINDOW_ALLOW_HIGHDPI on a platform with high-DPI support (Apple calls this "Retina"), and not disabled by the SDL_HINT_VIDEO_HIGHDPI_DISABLED hint.
Version
This function is available since SDL 2.0.1.
