The FsRtlIsNameInUnUpcasedExpression routine determines whether a Unicode string matches the specified pattern. Unlike the FsRtlIsNameInExpression routine, FsRtlIsNameInUnUpcasedExpression does not expect the Expression to be in upper case if IgnoreCase is TRUE.
ExpressionA pointer to the pattern string. Can contain wildcard characters. If IgnoreCase is TRUE, Expression must be lowercase.
NameA pointer to the string to be compared against the pattern. Cannot contain wildcard characters.
IgnoreCaseSet to TRUE for case-insensitive matching, FALSE otherwise.
UpcaseTableOptional pointer to uppercase character table to use for case-insensitive matching. If this value is not supplied, the default system uppercase character table is used.
Returns TRUE if the string matches the pattern, FALSE otherwise.
The following wildcard characters can be used in the pattern string:
| Wildcard character | Meaning |
|---|---|
| * (asterisk) | Matches zero or more characters. |
| ? (question mark) | Matches a single character. |
| DOS_DOT | Matches either a period or zero characters beyond the name string. |
| DOS_QM | Matches any single character or, upon encountering a period or end of name string, advances the expression to the end of the set of contiguous DOS_QMs. |
| DOS_STAR | Matches zero or more characters until encountering and matching the final period in the name. |
Note
If only one of the string parameters has a length of zero, FsRtlIsNameInUnUpcasedExpression returns FALSE. This means that "*" does not match a null string. If both parameters are null strings, FsRtlIsNameInUnUpcasedExpression returns TRUE.
