FILE_STANDARD_INFORMATION_EX structure (wdm.h)
The FILE_STANDARD_INFORMATION_EX structure is used as an argument to routines that query or set file information.
Syntax
typedef struct _FILE_STANDARD_INFORMATION_EX {
LARGE_INTEGER AllocationSize;
LARGE_INTEGER EndOfFile;
ULONG NumberOfLinks;
BOOLEAN DeletePending;
BOOLEAN Directory;
BOOLEAN AlternateStream;
BOOLEAN MetadataAttribute;
} FILE_STANDARD_INFORMATION_EX, *PFILE_STANDARD_INFORMATION_EX;
Members
AllocationSize
The file allocation size in bytes. Usually, this value is a multiple of the sector or cluster size of the underlying physical device.
EndOfFile
The end of file location as a byte offset.
NumberOfLinks
The number of hard links to the file.
DeletePending
The delete pending status. TRUE indicates that a file deletion has been requested.
Directory
The file directory status. TRUE indicates the file object represents a directory.
AlternateStream
The alternate data stream status. TRUE indicates the file object represents an alternate data stream.
MetadataAttribute
The metadata attribute status. TRUE indicates the file object represents a metadata attribute.
Remarks
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; that is, it is the offset to the byte immediately following the last valid byte in the file.
