TOKEN_STATISTICS

The TOKEN_STATISTICS structure contains information about an access token. An application can retrieve this information by calling the GetTokenInformation function.

typedef struct _TOKEN_STATISTICS { // tst 
    LUID  TokenId; 
    LUID  AuthenticationId; 
    LARGE_INTEGER ExpirationTime; 
    TOKEN_TYPE    TokenType; 
    SECURITY_IMPERSONATION_LEVEL ImpersonationLevel; 
    DWORD DynamicCharged; 
    DWORD DynamicAvailable; 
    DWORD GroupCount; 
    DWORD PrivilegeCount; 
    LUID  ModifiedId; 
} TOKEN_STATISTICS;

Members

TokenId: Specifies a locally unique identifier (LUID) that identifies this instance of the token object.
AuthenticationId: Specifies an LUID assigned to the session this token represents. There can be many tokens representing a single logon session.
ExpirationTime: Specifies the time at which this token expires. Expiration times for access tokens are not supported in the current version of Windows NT.
TokenType: Specifies a TOKEN_TYPE enumerated type indicating whether the token is a primary or impersonation token.
ImpersonationLevel: Specifies a SECURITY_IMPERSONATION_LEVEL enumerated type indicating the impersonation level of the token. This member is valid only if the TokenType is TokenImpersonation.
DynamicCharged: Specifies the amount, in bytes, of memory allocated for storing default protection and a primary group identifier.
DynamicAvailable: Specifies the portion of memory allocated for storing default protection and a primary group identifier not already in use. This value is returned as a count of free bytes.
GroupCount: Specifies the number of supplemental group security identifiers (SIDs) included in the token.
PrivilegeCount: Specifies the number of privileges included in the token.
ModifiedId: Specifies an LUID that changes each time the token is modified. An application can use this value as a test of whether a security context has changed since it was last used.
