SDL_OpenStorage - Opens up a container using a client-provided storage interface.

       This function is available since SDL 3.2.0.

       Applications  do  not  need  to  use  this  function  unless  they  are  providing  their own SDL_Storage
       implementation. If you just need an SDL_Storage, you should use the built-in implementations in SDL, like
       SDL_OpenTitleStorage() or SDL_OpenUserStorage().

       This function makes a copy of iface and the caller does not need to keep it around after this call.

iface  the interface that implements this storage, initialized using SDL_INIT_INTERFACE().

       userdata
              the pointer that will be passed to the interface functions.
