SDL_StorageInterface - Function interface for SDL_Storage.

       This struct is available since SDL 3.2.0.

       Apps  that  want  to supply a custom implementation of SDL_Storage will fill in all the functions in this
       struct, and then pass it to SDL_OpenStorage to create a custom SDL_Storage object.

       It is not usually necessary to do this; SDL provides standard implementations for many things  you  might
       expect to do with an SDL_Storage.

       This structure should be initialized using SDL_INIT_INTERFACE()
