If you use Import_Valued_Procedure (in GNAT), then you may not need to
use pointers at all:

procedure Get_Object
  (Return_Value :    out Int;  
   In_Param     : in     A_Type; 
   Out_Param    :    out Another_Type);

pragma Import_Valued_Procedure (Get_Object, "getObject");
   --or something like that
