sdlGetRenderLogicalPresentation function

bool sdlGetRenderLogicalPresentation(
  1. Pointer<SdlRenderer> renderer,
  2. Pointer<Int32> w,
  3. Pointer<Int32> h,
  4. Pointer<Int32> mode,
)

Get device independent resolution and presentation mode for rendering.

This function gets the width and height of the logical rendering output, or the output size in pixels if a logical resolution is not enabled.

Each render target has its own logical presentation state. This function gets the state for the current render target.

\param renderer the rendering context. \param w an int to be filled with the width. \param h an int to be filled with the height. \param mode the presentation mode used. \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 3.2.0.
