FILE_EA_INFORMATION structure (ntifs.h)

  • Article

The FILE_EA_INFORMATION structure is used to query for the size of the extended attributes (EA) for a file.

Syntax

typedef struct _FILE_EA_INFORMATION {
  ULONG EaSize;
} FILE_EA_INFORMATION, *PFILE_EA_INFORMATION;

Members

EaSize

Specifies the combined length, in bytes, of the extended attributes for the file.

Remarks

This structure is used by the ZwQueryInformationFile routine.

An extended attribute is a piece of application-specific metadata that an application can associate with a file that is not part of the file's data. In addition to the built-in attributes of a file, such as creation and modification times, applications can add non-file system attributes, such as the author's name and a description of the file content.

Requirements
