FILE_FULL_EA_INFORMATION structure (wdm.h)

The FILE_FULL_EA_INFORMATION structure provides extended attribute (EA) information.

Syntax

typedef struct _FILE_FULL_EA_INFORMATION {
  ULONG  NextEntryOffset;
  UCHAR  Flags;
  UCHAR  EaNameLength;
  USHORT EaValueLength;
  CHAR   EaName[1];
} FILE_FULL_EA_INFORMATION, *PFILE_FULL_EA_INFORMATION;

Members

NextEntryOffset

The offset of the next FILE_FULL_EA_INFORMATION-type entry. This member is zero if no other entries follow this one.

Flags

Can be zero or can be set with FILE_NEED_EA, indicating that the file to which the EA belongs cannot be interpreted without understanding the associated extended attributes.

EaNameLength

The length in bytes of the EaName array. This value does not include a null-terminator to EaName.

EaValueLength

The length in bytes of each EA value in the array.

EaName[1]

An array of characters naming the EA for this entry.

Remarks

This structure is longword-aligned. If a set of FILE_FULL_EA_INFORMATION entries is buffered, NextEntryOffset value in each entry, except the last, falls on a longword boundary.

The value(s) associated with each entry follows the EaName array. That is, an EA's values are located at EaName + (EaNameLength + 1).
