SDL_RenderSetClipRect, SDL_RenderIsClipEnabled and Render clipping availability

Hello. I’m developing a scroll area and I was planning in implementing it
using SDL_RenderSetClipRect, but then I saw SDL_RenderIsClipEnabled 1.
This function doesn’t seem to be available, and I was wondering what is it
for.

Is it for checking if the Renderer support clipping, or for users to check
if RenderSetClipRect was called? (Cause, you know, RenderGetClipRect can’t
tell if there’s clipping going on or not).

This made me ask myself, is there any platform where render clipping isn’t
avalilable?

Thanks.
