REG_UNLOAD_KEY_INFORMATION structure
The REG_UNLOAD_KEY_INFORMATION structure contains information that a driver's RegistryCallback routine can use when a registry hive is unloaded.
Syntax
typedef struct _REG_UNLOAD_KEY_INFORMATION {
PVOID Object;
PVOID UserEvent;
PVOID CallContext;
PVOID ObjectContext;
PVOID Reserved;
} REG_UNLOAD_KEY_INFORMATION, *PREG_UNLOAD_KEY_INFORMATION;
Members
- Object
-
A pointer to the registry key object for the key to be unloaded.
- UserEvent
-
A pointer to an event object.
- CallContext
-
Optional driver-defined context information that the driver's RegistryCallback routine can supply. This member is defined for Windows Vista and later versions of the Windows operating system.
- ObjectContext
-
A pointer to driver-defined context information that the driver has associated with a registry object by calling CmSetCallbackObjectContext. This member is defined for Windows Vista and later versions of the Windows operating system.
- Reserved
-
This member is reserved for future use. This member is defined for Windows Vista and later versions of the Windows operating system.
Remarks
The system passes the REG_UNLOAD_KEY_INFORMATION structure to the RegistryCallback routine every time a thread attempts to unload a key—for example, when a user-mode thread calls RegUnloadKey.
