Description

IncrementalCompareString creates 2 compare keys from the strings AStrA and AStrB using collation data in ACollation. The keys are computed only to the point where the two strings differ. This means the keys cannot be reused for other comparisons if the strings differ. The two strings can be specified as a unicode string or as a pointer to a null-terminated character array with a length (ALengthA and ALengthB). It returns then the result of CompareSortKey .

Errors

None.
