SDL_ReadSurfacePixel - Retrieves a single pixel from a surface.

       This function is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10                            SDL_ReadSurfacePixel(3)

       This  function prioritizes correctness over speed: it is suitable for unit tests, but is not intended for
       use in a game engine.

       Like SDL_GetRGBA , this uses the entire 0..255 range when converting color components from pixel  formats
       with less than 8 bits per RGB component.

surface
              the surface to read.

       x      the horizontal coordinate, 0 <= x < width.

       y      the vertical coordinate, 0 <= y < height.

       r      a pointer filled in with the red channel, 0-255, or NULL to ignore this channel.

       g      a pointer filled in with the green channel, 0-255, or NULL to ignore this channel.

       b      a pointer filled in with the blue channel, 0-255, or NULL to ignore this channel.

       a      a pointer filled in with the alpha channel, 0-255, or NULL to ignore this channel.
