Description

CompareOrdinal compares 2 strings A and B bytewise. It is faster than a regular compare, but offers less options.

0 if the strings are equal a negative number if A < B a positive number if A > B

Optionally, a zero-based starting index for the compare can be given for each of the strings: IndexA and IndexB. In this case a maximum amount of characters (ALen) to be compared must also be specified.

Errors

None.
