REG_DELETE_VALUE_KEY_INFORMATION structure (wdm.h)
The REG_DELETE_VALUE_KEY_INFORMATION structure contains information that a driver's RegistryCallback routine can use when a registry key's value is being deleted.
Syntax
typedef struct _REG_DELETE_VALUE_KEY_INFORMATION {
PVOID Object;
PUNICODE_STRING ValueName;
PVOID CallContext;
PVOID ObjectContext;
PVOID Reserved;
} REG_DELETE_VALUE_KEY_INFORMATION, *PREG_DELETE_VALUE_KEY_INFORMATION;
Members
Object
A pointer to the registry key object for the key whose value entry is about to be deleted.
ValueName
A pointer to a UNICODE_STRING structure that contains the name of the value entry that is about to be deleted.
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 this structure to the RegistryCallback routine every time a thread attempts to delete a value entry—for example, when a user-mode thread calls RegDeleteValue or when a driver calls ZwDeleteValueKey.
