SDL_GetError() output is empty, when SDL_ReadU8 returns false #11395

SDL3 wiki says: call SDL_GetError() for more information.

#include <SDL3/SDL.h>
#include <stdio.h>

int main(int argc, char **argv)
{
    SDL_Init(SDL_INIT_VIDEO);

    SDL_IOStream *io = SDL_IOFromFile("empty_file", "rb");

    Uint8 c;

    if (SDL_ReadU8(io, &c) == false)
        printf("test: %s\n", SDL_GetError());
}

test:

Should empty output be interpreted as end of stream?

The documentation should mention using SDL_GetIOStatus to check whether EOF was reached or an error actually happened.
