WDF_DEVICE_PNP_NOTIFICATION_DATA structure
[Applies to KMDF only]
The WDF_DEVICE_PNP_NOTIFICATION_DATA structure describes a state change within a device's Plug and Play state machine.
Syntax
typedef struct _WDF_DEVICE_PNP_NOTIFICATION_DATA { WDF_STATE_NOTIFICATION_TYPE Type; union { struct { WDF_DEVICE_PNP_STATE CurrentState; WDF_DEVICE_PNP_STATE NewState; } EnterState; struct { WDF_DEVICE_PNP_STATE CurrentState; } PostProcessState; struct { WDF_DEVICE_PNP_STATE CurrentState; WDF_DEVICE_PNP_STATE NewState; } LeaveState; } Data; } WDF_DEVICE_PNP_NOTIFICATION_DATA;
Members
- Type
-
A WDF_STATE_NOTIFICATION_TYPE-typed enumerator that identifies the type of state change that is being reported.
- Data
-
- EnterState
-
- CurrentState
-
If Type is StateNotificationEnterState, this WDF_DEVICE_PNP_STATE-typed enumerator identifies the state machine's current state.
- NewState
-
If Type is StateNotificationEnterState, this WDF_DEVICE_PNP_STATE-typed enumerator identifies the state machine's next state.
- PostProcessState
-
- CurrentState
-
If Type is StateNotificationEnterState, this WDF_DEVICE_PNP_STATE-typed enumerator identifies the state machine's current state.
- LeaveState
-
- CurrentState
-
If Type is StateNotificationEnterState, this WDF_DEVICE_PNP_STATE-typed enumerator identifies the state machine's current state.
- NewState
-
If Type is StateNotificationEnterState, this WDF_DEVICE_PNP_STATE-typed enumerator identifies the state machine's next state.
Remarks
The WDF_DEVICE_PNP_NOTIFICATION_DATA structure is an input argument to a driver's EvtDevicePnpStateChange callback function.
