Description

Compares two strings, with case sensitivity.

CompareStr compares S1 to S2, with case sensitivity. The return value is less than 0 if S1 is less than S2, 0 if S1 equals S2, or greater than 0 if S1 is greater than S2. The comparison operation is based on the 16-bit ordinal value of each character and is not affected by the current locale, when using the first CompareStr overloaded method.

The LocaleOptions parameter of the second CompareStr overloaded method is of type TLocaleOptions and defines a choice of dependent and independent locale options. For more information, please refer to the TLocaleOptions topic.
