Get the output size in pixels of a rendering context.


int SDL_GetRendererOutputSize(SDL_Renderer * renderer,
                              int *w, int *h);

Function Parameters


the rendering context


an int filled with the width


an int filled with the height

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.


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.


This function is available since SDL 2.0.0.
