OB_CALLBACK_REGISTRATION structure
The OB_CALLBACK_REGISTRATION structure specifies the parameters when the ObRegisterCallbacks routine registers ObjectPreCallback and ObjectPostCallback callback routines.
Syntax
typedef struct _OB_CALLBACK_REGISTRATION { USHORT Version; USHORT OperationRegistrationCount; UNICODE_STRING Altitude; PVOID RegistrationContext; OB_OPERATION_REGISTRATION *OperationRegistration; } OB_CALLBACK_REGISTRATION, *POB_CALLBACK_REGISTRATION;
Members
- Version
-
The version of object callback registration that is requested. Drivers should specify OB_FLT_REGISTRATION_VERSION.
- OperationRegistrationCount
-
The number of entries in the OperationRegistration array.
- Altitude
-
A Unicode string that specifies the altitude of the driver. For more information about altitude, see Load Order Groups and Altitudes for Minifilter Drivers.
- RegistrationContext
-
The system passes the RegistrationContext value to the callback routine when the callback routine is run. The meaning of this value is driver-defined.
- OperationRegistration
-
A pointer to an array of OB_OPERATION_REGISTRATION structures. Each structure specifies ObjectPreCallback and ObjectPostCallback callback routines and the types of operations that the routines are called for.
