REG_DELETE_KEY_INFORMATION structure (wdm.h)

  • Article

The REG_DELETE_KEY_INFORMATION structure contains information that a driver's RegistryCallback routine can use when a registry key is being deleted.

Syntax

typedef struct _REG_DELETE_KEY_INFORMATION {
  PVOID Object;
  PVOID CallContext;
  PVOID ObjectContext;
  PVOID Reserved;
} REG_DELETE_KEY_INFORMATION, *PREG_DELETE_KEY_INFORMATION, REG_FLUSH_KEY_INFORMATION, *PREG_FLUSH_KEY_INFORMATION;

Members

Object

A pointer to the registry key object for the key 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 key—for example, when a user-mode thread calls RegDeleteKey or RegDeleteKeyEx or when a driver calls ZwDeleteKey.
