bool sdlGetRenderViewport(
  1. Pointer<SdlRenderer> renderer,
  2. Pointer<SdlRect> rect
)

Get the drawing area for the current target.

Each render target has its own viewport. This function gets the viewport for the current render target.

\param renderer the rendering context. \param rect an SDL_Rect structure filled in with the current drawing area. \returns true on success or false on failure; call SDL_GetError() for more information.
