The result is -1,0,+1 for Left<Right, Left=Right, -- Left>Right respectively. This function works with 4 byte words -- if the operands are aligned on 4-byte boundaries and long enough. function Str_Compare_Bytes (Left : System.Address; Right : System.Address; Left_Len : Natural; Right_Len : Natural) return Integer; -- Same functionality as Str_Compare but always proceeds by bytes. -- Used when the caller knows that the operands are unaligned, or -- short enough that it makes no sense to go by words. end System.String_Compare;
