View the official Windows Driver Kit DDI referenceNo description available.
The caller-allocated FILTER_VOLUME_STANDARD_INFORMATION structure contains information for a volume.
NextEntryOffsetRead-only offset, in bytes, of the next FILTER_VOLUME_STANDARD_INFORMATION structure if multiple structures are present in the buffer. This member is zero if no other structures follow this one.
FlagsA read-only bitmask of system-defined flags that describe attributes of the volume. The following are valid flag values.
| Flag | Meaning |
|---|---|
| FLTFL_VSI_DETACHED_VOLUME | The volume in not currently attached to a storage stack. |
FrameIDRead-only member used to identify the filter manager frame that the volume is in.
FileSystemTypeRead-only member used to identify the type of file system being used on the volume. The possible values for this member are listed in FLT_FILESYSTEM_TYPE.
FilterVolumeNameLengthRead-only length, in bytes, of the volume name.
FilterVolumeNameRead-only name of the volume of FilterVolumeNameLength length. This Unicode string is not NULL-terminated.
Filter manager enumeration routines, such as FltEnumerateVolumeInformation, can fill a buffer with structures of type FILTER_VOLUME_STANDARD_INFORMATION where each structure represents a volume known to filter manager. This list of structures can contain multiple volumes with the same name. For more information, see Understanding Volume Enumerations with Duplicate Volume Names.
The FILTER_VOLUME_STANDARD_INFORMATION structure must be aligned on a LONGLONG (8-byte) boundary. If a buffer contains two or more of these structures, the NextEntryOffset value in each entry falls on an 8-byte boundary.
A FILTER_VOLUME_STANDARD_INFORMATION structure can be allocated from paged or nonpaged pool.
