TOKEN_STATISTICS info  Overview  Group

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.
