sdlGetRenderOutputSize function

bool sdlGetRenderOutputSize(Pointer<SdlRenderer> renderer, Pointer<Int32> w, Pointer<Int32> h)

Get the output size in pixels of a rendering context.

This returns the true output size in pixels, ignoring any render targets or logical size and presentation.

\param renderer the rendering context. \param w a pointer filled in with the width in pixels. \param h a pointer filled in with the height in pixels. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.1.3.
