sdlGetRenderMetalLayer function render

Pointer<NativeType> sdlGetRenderMetalLayer(Pointer<SdlRenderer> renderer)

Get the CAMetalLayer associated with the given Metal renderer.

This function returns void *, so SDL doesn't have to include Metal's headers, but it can be safely cast to a CAMetalLayer *.

\param renderer the renderer to query. \returns a CAMetalLayer * on success, or NULL if the renderer isn't a Metal renderer.

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

\since This function is available since SDL 3.2.0.
