--  This package contains functions for runtime comparisons on arrays whose

package System.Compare_Array_Unsigned_32 is

   --  Note: although the functions in this package are in a sense Pure, the
   --  package cannot be declared as Pure, since the arguments are addresses,
   --  not the data, and the result is not pure wrt the address values.

   function Compare_Array_U32
     (Left      : System.Address;
      Right     : System.Address;
      Left_Len  : Natural;
      Right_Len : Natural) return Integer;
   --  Compare the array starting at address Left of length Left_Len
   --  with the array starting at address Right of length Right_Len.
   --  The comparison is in the normal Ada semantic sense of array
   --  comparison. The result is -1,0,+1 for Left<Right, Left=Right,
   --  Left>Right respectively.
