SDL_AddGamepadMappingsFromIO - Load a set of gamepad mappings from an SDL_IOStream .

       This function is available since SDL 3.2.0.

       You can call this function several times, if needed, to load different database files.

       If  a  new  mapping is loaded for an already known gamepad GUID, the later version will overwrite the one
       currently loaded.

       Any new mappings for already plugged in controllers will generate

       SDL_EVENT_GAMEPAD_ADDED
        events.

       Mappings not belonging to the current platform or with no platform field specified will be ignored  (i.e.
       mappings for Linux will be ignored in Windows, etc).

       This  function  will  load  the  text database entirely in memory before processing it, so take this into
       consideration if you are in a memory constrained environment.

src    the data stream for the mappings to be added.

       closeio
              if true, calls SDL_CloseIO () on src before returning, even in the case of an error.
