FILE_STANDARD_INFORMATION structure (wdm.h)

The FILE_STANDARD_INFORMATION structure is used as an argument to routines that query or set file information.

Syntax

typedef struct _FILE_STANDARD_INFORMATION {
  LARGE_INTEGER AllocationSize;
  LARGE_INTEGER EndOfFile;
  ULONG         NumberOfLinks;
  BOOLEAN       DeletePending;
  BOOLEAN       Directory;
} FILE_STANDARD_INFORMATION, *PFILE_STANDARD_INFORMATION;

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.

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.
