Function SDL_GetRenderDriver 

Source 
pub unsafe extern "C" fn SDL_GetRenderDriver(
    index: c_int,
) -> *const c_char
Expand description

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

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.

Parameter: index the index of the rendering driver; the value ranges from 0 to SDL_GetNumRenderDrivers() - 1. Returns: the name of the rendering driver at the requested index, or NULL if an invalid index was specified.

Thread Safety: It is safe to call this function from any thread.

Available Since: This function is available since SDL 3.2.0.
