Summary: Contains information about a set of privileges for an access token.

!!!!C# Definitions:
 public const UInt32 SE_PRIVILEGE_ENABLED_BY_DEFAULT	= 0x00000001;
 public const UInt32 SE_PRIVILEGE_ENABLED		= 0x00000002;
 public const UInt32 SE_PRIVILEGE_REMOVED		= 0x00000004;
 public const UInt32 SE_PRIVILEGE_USED_FOR_ACCESS	= 0x80000000;

public struct TOKEN_PRIVILEGES {
 	public UInt32 PrivilegeCount;
 	[MarshalAs(UnmanagedType.ByValArray, SizeConst=ANYSIZE_ARRAY)]
 	public LUID_AND_ATTRIBUTES [] Privileges;
 }

Alternate simple structure for single privilege setting:

[StructLayout(LayoutKind.Sequential)]
 public struct TOKEN_PRIVILEGES
 {
 	public UInt32 PrivilegeCount;
 	public LUID Luid;
 	public UInt32 Attributes;
 }
!!!!VB Definition:
 Structure TOKEN_PRIVILEGES 
   Public PrivilegeCount As Integer
   Public TheLuid As LUID
   Public Attributes As Integer
 End Structure
!!!!User-Defined Field Types:
[LUID]
[LUID_AND_ATTRIBUTES]
[WINNT] (for ANYSIZE_ARRAY)

!!!!Notes:

Do NOT define LUID as UInt64! Use the structure LUID consisted of two UInt32 because of memory alignment.

!!!!VB.Net Sample Code:
   ' Token Privilege
   Dim tp As New TOKEN_PRIVILEGES

tp.PrivilegeCount = 1
   tp.TheLuid = luid_Restore
   tp.Attributes = SE_PRIVILEGE_ENABLED
