Description

AnsiStrComp compares S1 to S2, with case sensitivity. The compare operation is controlled by the current locale. The return value is:

Condition	Return Value
S1 > S2	> 0
S1 < S2	< 0
S1 = S2	= 0

Note: Most locales consider lowercase characters to be less than the corresponding uppercase characters. This is in contrast to ASCII order, in which lowercase characters are greater than uppercase characters.

Note: This function supports multi-byte character sets (MBCS).
