Function sdl2_sys::SDL_GetRendererOutputSize

pub unsafe extern "C" fn SDL_GetRendererOutputSize(
    renderer: *mut SDL_Renderer,
    w: *mut c_int,
    h: *mut c_int
) -> c_int

Get the output size in pixels of a rendering context.

Due to high-dpi displays, you might end up with a rendering context that has more pixels than the window that contains it, so use this instead of SDL_GetWindowSize() to decide how much drawing area you have.

\param renderer the rendering context \param w an int filled with the width \param h an int filled with the height \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
