Routine Description:
|
|
|
|
This function will validate the path against the specified criteria. This can include
|
|
whether it is local or not, whether it is NTFS, etc.
|
|
|
|
If the function returns success, the MatchingCriteria can be examined to find out which
|
|
of the ValidationCriteria are set
|
|
|
|
Arguments:
|
|
|
|
Path - Path to validate
|
|
|
|
ValidationCriteria - What to check for. Refer to DSROLEP_PATH_VALIDATE_*.
|
|
|
|
MatchingCriteria - This is where the indications of validity are returned. If the path
|
|
meets the check, the corresponding bit from the ValidationCriteria is turned on
|
|
here.
|
|
|
|
|
|
Returns:
|
|
|
|
ERROR_SUCCESS - Success
