No description available.
The FILE_BOTH_DIR_INFORMATION structure is used to query detailed information for the files in a directory.
NextEntryOffset
Byte offset of the next FILE_BOTH_DIR_INFORMATION entry, if multiple entries are present in a buffer. This member is zero if no other entries follow this one.
FileIndex
Byte offset of the file within the parent directory. This member is undefined for file systems, such as NTFS, in which the position of a file within the parent directory is not fixed and can be changed at any time to maintain sort order.
CreationTime
Time when the file was created.
LastAccessTime
Last time the file was accessed.
LastWriteTime
Last time information was written to the file.
ChangeTime
Last time the file was changed.
EndOfFile
Absolute new end-of-file position as a byte offset from the start of the file. EndOfFile specifies the byte offset to the end of the file. Because this value is zero-based, it actually refers to the first free byte in the file. In other words, EndOfFile is the offset to the byte immediately following the last valid byte in the file.
AllocationSize
File allocation size, in bytes. Usually, this value is a multiple of the sector or cluster size of the underlying physical device.
FileAttributes
File attributes, which can be any valid combination of the following:
FileNameLength
Specifies the length, in bytes, of the file name string.
EaSize
Combined length, in bytes, of the extended attributes (EA) for the file.
ShortNameLength
Specifies the length, in bytes, of the short file name string.
ShortName
Unicode string containing the short (8.3) name for the file.
FileName
Specifies the first character of the file name string. This is followed in memory by the remainder of the string.
This information can be queried in either of the following ways:
Call ZwQueryDirectoryFile, passing FileBothDirectoryInformation as the value of FileInformationClass and passing a caller-allocated, FILE_BOTH_DIR_INFORMATION-structured buffer as the value of FileInformation.
Create an IRP with major function code IRP_MJ_DIRECTORY_CONTROL and minor function code IRP_MN_QUERY_DIRECTORY.
No specific access rights are required to query this information.
All dates and times are in absolute system-time format. Absolute system time is the number of 100-nanosecond intervals since the start of the year 1601.
This 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, except the last, falls on an 8-byte boundary.
FsRtlNotifyFullChangeDirectory
This structure is documented in Windows Driver Kit.
Structure FILE_BOTH_DIR_INFORMATION
is returned as a result of call NtQueryDirectoryFile
with FileBothDirectoryInformation
information class. It's extended version of FILE_FULL_DIR_INFORMATION
structure,
additionally containing short file name. It's used in Win32 API calls FindFirstFile
and FindNextFile
.
Offset (in bytes) of next FILE_BOTH_DIR_INFORMATION
structure placed in result buffer. If there's no more entries, NextEntryOffset
is set to zero.
File index value, or zero, if directory indexing is not available.
Time of object creation.
Last access time. Means time when last open operation was performed.
Time of last write data.
Time of last change.
Specify length of file, in bytes.
Specify real size of file on device. It must be equal or greater to EndOfFile
member.
Attributes of file.
Length of FileName
array, in bytes.
Size of Extended Attributes associated with file. See also FILE_EA_INFORMATION
structure.
Length ShortName
array, in bytes.
Alternate file name, in UNICODE format. Empty string means:
8DOT3
(MS DOS) standard, and there's no reason to set the same name twice;UNICODE string specifying file name.
