The requests allow the client to search * for the file(s) which match the file specification. The search is * started with TRANS2_FIND_FIRST2 and can be continued if necessary with * TRANS2_FIND_NEXT2. There are numerous levels of information which may be * obtained for the returned files, the desired level is specified in the * InformationLevel field of the requests. * * InformationLevel Name Value * ================================= ================ * * SMB_INFO_STANDARD 1 * SMB_INFO_QUERY_EA_SIZE 2 * SMB_INFO_QUERY_EAS_FROM_LIST 3 * SMB_FIND_FILE_DIRECTORY_INFO 0x101 * SMB_FIND_FILE_FULL_DIRECTORY_INFO 0x102 * SMB_FIND_FILE_NAMES_INFO 0x103 * SMB_FIND_FILE_BOTH_DIRECTORY_INFO 0x104 * SMB_FIND_FILE_ID_FULL_DIRECTORY_INFO 0x105 * SMB_FIND_FILE_ID_BOTH_DIRECTORY_INFO 0x106 * * The following sections detail the data returned for each * InformationLevel. The requested information is placed in the Data * portion of the transaction response. Note: a client which does not * support long names can only request SMB_INFO_STANDARD. * * A four-byte resume key precedes each data item (described below) if bit * 2 in the Flags field is set, i.e. if the request indicates the server * should return resume keys. Note: it is not always the case. If the * data item already includes the resume key, the resume key should not be * added again. * * 4.3.4.1 SMB_INFO_STANDARD * * Response Field Description * ================================ ================================== * * SMB_DATE CreationDate; Date when file was created * SMB_TIME CreationTime; Time when file was created * SMB_DATE LastAccessDate; Date of last file access * SMB_TIME LastAccessTime; Time of last file access * SMB_DATE LastWriteDate; Date of last write to the file * SMB_TIME LastWriteTime; Time of last write to the file * ULONG DataSize; File Size * ULONG AllocationSize; Size of filesystem allocation unit * USHORT Attributes; File Attributes * UCHAR FileNameLength; Length of filename in bytes * STRING FileName; Name of found file * * 4.3.4.2 SMB_INFO_QUERY_EA_SIZE * * Response Field Description * ================================= ================================== * * SMB_DATE CreationDate; Date when file was created * SMB_TIME CreationTime; Time when file was created * SMB_DATE LastAccessDate; Date of last file access * SMB_TIME LastAccessTime; Time of last file access * SMB_DATE LastWriteDate; Date of last write to the file * SMB_TIME LastWriteTime; Time of last write to the file * ULONG DataSize; File Size * ULONG AllocationSize; Size of filesystem allocation unit * USHORT Attributes; File Attributes * ULONG EaSize; Size of file's EA information * UCHAR FileNameLength; Length of filename in bytes * STRING FileName; Name of found file * * 4.3.4.3 SMB_INFO_QUERY_EAS_FROM_LIST * * This request returns the same information as SMB_INFO_QUERY_EA_SIZE, but * only for files which have an EA list which match the EA information in * the Data part of the request. * * 4.3.4.4 SMB_FIND_FILE_DIRECTORY_INFO * * Response Field Description * ================================= ================================== * * ULONG NextEntryOffset; Offset from this structure to * beginning of next one * ULONG FileIndex; * LARGE_INTEGER CreationTime; file creation time * LARGE_INTEGER LastAccessTime; last access time * LARGE_INTEGER LastWriteTime; last write time * LARGE_INTEGER ChangeTime; last attribute change time * LARGE_INTEGER EndOfFile; file size * LARGE_INTEGER AllocationSize; size of filesystem allocation information * ULONG ExtFileAttributes; Extended file attributes * (see section 3.11) * ULONG FileNameLength; Length of filename in bytes * STRING FileName; Name of the file * * 4.3.4.5 SMB_FIND_FILE_FULL_DIRECTORY_INFO * * Response Field Description * ================================= ================================== * * ULONG NextEntryOffset; Offset from this structure to * beginning of next one * ULONG FileIndex; * LARGE_INTEGER CreationTime; file creation time * LARGE_INTEGER LastAccessTime; last access time * LARGE_INTEGER LastWriteTime; last write time * LARGE_INTEGER ChangeTime; last attribute change time * LARGE_INTEGER EndOfFile; file size * LARGE_INTEGER AllocationSize; size of filesystem allocation information * ULONG ExtFileAttributes; Extended file attributes * (see section 3.11) * ULONG FileNameLength; Length of filename in bytes * ULONG EaSize; Size of file's extended attributes * STRING FileName; Name of the file * * * SMB_FIND_FILE_ID_FULL_DIRECTORY_INFO * * This is the same as SMB_FIND_FILE_FULL_DIRECTORY_INFO but with * FileId inserted after EaSize.
