LUID_AND_ATTRIBUTES structure (wdm.h)
LUID_AND_ATTRIBUTES represents a locally unique identifier (LUID) and its attributes.
Syntax
typedef struct _LUID_AND_ATTRIBUTES {
LUID Luid;
ULONG Attributes;
} LUID_AND_ATTRIBUTES, *PLUID_AND_ATTRIBUTES;
Members
Luid
An LUID value.
Attributes
Specifies attributes of the LUID. This value contains up to 32 one-bit flags. Its meaning depends on the definition and use of the LUID.
The following attributes are defined for privileges:
| Attribute | Description |
|---|---|
| SE_PRIVILEGE_ENABLED | The privilege is enabled. |
| SE_PRIVILEGE_ENABLED_BY_DEFAULT | The privilege is enabled by default. |
| SE_PRIVILEGE_USED_FOR_ACCESS | The privilege was used to gain access to an object or service. This flag is used to identify the relevant privileges in a set passed by a client application that may contain unnecessary privileges. |
Remarks
An LUID_AND_ATTRIBUTES structure can represent an LUID whose attributes change frequently, such as when it is used to represent privileges in the PRIVILEGE_SET structure. Privileges are represented by LUIDs and have attributes indicating whether they are currently enabled or disabled.
Be aware of the following derived types:
typedef LUID_AND_ATTRIBUTES LUID_AND_ATTRIBUTES_ARRAY[ANYSIZE_ARRAY];
typedef LUID_AND_ATTRIBUTES_ARRAY *PLUID_AND_ATTRIBUTES_ARRAY;
