Contains access-control information for a specified trustee. This structure stores information equivalent to the access-control information stored in an ACE.

Syntax

typedef struct _ACTRL_ACCESS_ENTRYW {
  TRUSTEE_W     Trustee;
  ULONG         fAccessFlags;
  ACCESS_RIGHTS Access;
  ACCESS_RIGHTS ProvSpecificAccess;
  INHERIT_FLAGS Inheritance;
  LPWSTR        lpInheritProperty;
} ACTRL_ACCESS_ENTRYW, *PACTRL_ACCESS_ENTRYW;

Members

Trustee

A TRUSTEE structure that identifies the user, group, or program (such as a service) to which the access-control entry applies.

fAccessFlags

Indicates how the access rights specified by the Access and ProvSpecificAccess members apply to the trustee. This member can be one of the following values. If you are using this structure with the COM implementation of IAccessControl, this member must be ACTRL_ACCESS_ALLOWED or ACTRL_ACCESS_DENIED.

Value	Meaning
ACTRL_ACCESS_ALLOWED 0x00000001	The rights are allowed.
ACTRL_ACCESS_DENIED 0x00000002	The rights are denied.
ACTRL_AUDIT_SUCCESS 0x00000004	The system generates audit messages for failed attempts to use the rights.
ACTRL_AUDIT_FAILURE 0x00000008	The system generates audit messages for successful attempts to use the rights.

Access

A bitmask that specifies the access rights that the entry allows, denies, or audits for the trustee.

This member must use the provider-independent access flags, such as ACTRL_READ_CONTROL, rather than access flags such as READ_CONTROL. The provider for the object type converts these provider-independent flags to the corresponding provider-specific flags.

If you are using this structure with the COM implementation of IAccessControl, this member must be COM_RIGHTS_EXECUTE.

ACTRL_SYSTEM_ACCESS

ACTRL_DELETE

ACTRL_READ_CONTROL

ACTRL_CHANGE_ACCESS

ACTRL_CHANGE_OWNER

ACTRL_SYNCHRONIZE

ACTRL_STD_RIGHTS_ALL

ACTRL_STD_RIGHT_REQUIRED

COM_RIGHTS_EXECUTE

COM_RIGHTS_EXECUTE_LOCAL

COM_RIGHTS_EXECUTE_REMOTE

COM_RIGHTS_ACTIVATE_LOCAL

COM_RIGHTS_ACTIVATE_REMOTE

ProvSpecificAccess

A bitmask that specifies access rights specific to the provider type. The functions that use the ACTRL_ACCESS_ENTRY structure pass these bits on to the provider without interpreting them. In most cases, this member should be 0.

Inheritance

A set of bit flags that determines whether other containers or objects can inherit the access-control entry from the primary object to which the access list is attached. If you are using this structure with the COM implementation of IAccessControl, this value must be NO_INHERITANCE, which indicates that the access-control entry is not inheritable. Otherwise, this value can be NO_INHERITANCE or it can be a combination of the following values.

Value	Meaning
CONTAINER_INHERIT_ACE 0x2	Other containers that are contained by the primary object inherit the entry.
INHERIT_ONLY_ACE 0x8	The ACE does not apply to the primary object to which the ACL is attached, but objects contained by the primary object inherit the entry.
NO_PROPAGATE_INHERIT_ACE 0x4	The OBJECT_INHERIT_ACE and CONTAINER_INHERIT_ACE flags are not propagated to an inherited entry.
OBJECT_INHERIT_ACE 0x1	Noncontainer objects contained by the primary object inherit the entry.
SUB_CONTAINERS_AND_OBJECTS_INHERIT 0x3	Both containers and noncontainer objects that are contained by the primary object inherit the entry. This flag corresponds to the combination of the CONTAINER_INHERIT_ACE and OBJECT_INHERIT_ACE flags.
SUB_CONTAINERS_ONLY_INHERIT 0x2	Other containers that are contained by the primary object inherit the entry. This flag corresponds to the CONTAINER_INHERIT_ACE flag.
SUB_OBJECTS_ONLY_INHERIT 0x1	Noncontainer objects contained by the primary object inherit the entry. This flag corresponds to the OBJECT_INHERIT_ACE flag.

lpInheritProperty

A pointer to a null-terminated string that identifies the object types that can inherit the entry. If you are using this structure with the COM implementation of IAccessControl, this member must be NULL.

Remarks

Note

The accctrl.h header defines ACTRL_ACCESS_ENTRY as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
