Looking in cifspdu.h, there are a number of things that it might be possible
|
|
to use.
|
|
|
|
(1) FILE_ALL_INFO: CreationTime, IndexNumber, IndexNumber1, FileName
|
|
(assuming this isn't flattened to '\' or something for the root of a
|
|
share.
|
|
|
|
(2) FILE_UNIX_BASIC_INFO: DevMajor, DevMinor, UniqueId.
|
|
|
|
(3) FILE_INFO_STANDARD: CreationDate, CreationTime.
|
|
|
|
(4) FILE_INFO_BASIC: CreationTime.
|
|
|
|
(5) FILE_DIRECTORY_INFO: FileIndex, CreationTime, FileName.
|
|
|
|
(6) SEARCH_ID_FULL_DIR_INFO: FileIndex, CreationTime, UniqueId, FileName.
|
|
|
|
(7) FILE_BOTH_DIRECTORY_INFO: FileIndex, CreationTime, ShortName, FileName.
|
|
|
|
(8) OPEN_RSP_EXT: Fid, CreationTime, VolumeGUID, FileId.
|
|
|
|
You may have to choose different sets of things, depending on what the server
|
|
has on offer. Also, don't forget, if you can't work out whether a share is
|
|
coherent or not from the above, you can always use LastWriteTime, ChangeTime
|
|
and EndOfFile and just discard the whole subtree if they differ.
