SDL_GetRenderDriver - Use this function to get the name of a built in 2D rendering driver.

       This function is available since SDL 3.2.0.

       The  list  of  rendering drivers is given in the order that they are normally initialized by default; the
       drivers that seem more reasonable to choose first (as far as the SDL developers believe) are  earlier  in
       the list.

       The names of drivers are all simple, low-ASCII identifiers, like "opengl", "direct3d12" or "metal". These
       never have Unicode characters, and are not meant to be proper names.

index  the index of the rendering driver; the value ranges from 0 to SDL_GetNumRenderDrivers () - 1.
