Function SDL_GetRenderDriver 

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

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.

Parameters

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

Return value

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.

Availability

This function is available since SDL 3.2.0.
