+-- This package contains functions for runtime comparisons on strings
+
+pragma Compiler_Unit;
+
+package System.String_Compare is
+
+ function Str_Compare
+ (Left : System.Address;
+ Right : System.Address;
+ Left_Len : Natural;
+ Right_Len : Natural) return Integer;
+ -- Compare the string starting at address Left of length Left_Len
+ -- with the string starting at address Right of length Right_Len.
+ -- The comparison is in the normal Ada semantic sense of string
+ -- comparison. 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.
