Expand description

Get device independent resolution for rendering.

When using the main rendering target (eg no target texture is set): this may return 0 for w and h if the SDL_Renderer has never had its logical size set by SDL_RenderSetLogicalSize(). Otherwise it returns the logical width and height.

When using a target texture: Never return 0 for w and h at first. Then it returns the logical width and height that are set.

\param renderer a rendering context \param w an int to be filled with the width \param h an int to be filled with the height

\since This function is available since SDL 2.0.0.
