SDL_GetKeyState - I am confused

SDL Development
1

I always called SDL_GetKeyState every frame. Now someone asked on irc should he
call it every frame, and SoM says: no.
I know this function gives pointer to array, but can we be sure this pointer
never changes? I think this is question about API, not current implementation.–

It is safe (and inexpensive) to call SDL_GetKeyState() every frame.
This is the correct way of doing it.

The current implementation uses a single internal array, and will continue
to do so for all SDL 1.2.x releases.
