FILE_ALL_INFORMATION structure (ntifs.h)

  • Article

The FILE_ALL_INFORMATION structure is a container for several FILE_XXX_INFORMATION structures.

Syntax

typedef struct _FILE_ALL_INFORMATION {
  FILE_BASIC_INFORMATION     BasicInformation;
  FILE_STANDARD_INFORMATION  StandardInformation;
  FILE_INTERNAL_INFORMATION  InternalInformation;
  FILE_EA_INFORMATION        EaInformation;
  FILE_ACCESS_INFORMATION    AccessInformation;
  FILE_POSITION_INFORMATION  PositionInformation;
  FILE_MODE_INFORMATION      ModeInformation;
  FILE_ALIGNMENT_INFORMATION AlignmentInformation;
  FILE_NAME_INFORMATION      NameInformation;
} FILE_ALL_INFORMATION, *PFILE_ALL_INFORMATION;

Members

BasicInformation

Contains basic information about the file, which includes the file attributes and the file creation time. This member is a FILE_BASIC_INFORMATION structure.

StandardInformation

Contains standard information about a file, which includes the file allocation size, the end-of-file offset, and whether the file is a directory. This member is a FILE_STANDARD_INFORMATION structure.

InternalInformation

Contains the 8-byte file reference number for the file. This member is a FILE_INTERNAL_INFORMATION structure.

EaInformation

Specifies the size of the extended attributes of the file. This member is a FILE_EA_INFORMATION structure.

AccessInformation

Specifies the client's access rights to the file. This member is a FILE_ACCESS_INFORMATION structure.

PositionInformation

Specifies the current file position. This member is a FILE_POSITION_INFORMATION structure.

ModeInformation

Specifies the access mode in which the file was created or opened. This member is a FILE_MODE_INFORMATION structure.

AlignmentInformation

Specifies the device's memory address alignment requirement for data transfers. This member is a FILE_ALIGNMENT_INFORMATION structure.

NameInformation

Contains the file name. This member is a FILE_NAME_INFORMATION structure. This structure contains the first character in the file name string. The additional characters in the file name string immediately follow the structure. To accommodate the full file name, the buffer that is allocated to contain a FILE_ALL_INFORMATION structure must be large enough to contain both the structure and the part of the file name string that follows the structure.

Remarks

This structure is used by the ZwQueryInformationFile routine.

FILE_ALL_INFORMATION combines several file-information structures into a single structure to reduce the number of queries that are required to obtain information about a file.
