WdfDeviceSetDeviceState function

[Applies to KMDF and UMDF]

The WdfDeviceSetDeviceState method sets the device state for a specified device.

Syntax

VOID WdfDeviceSetDeviceState(
  _In_ WDFDEVICE         Device,
  _In_ PWDF_DEVICE_STATE DeviceState
);

Parameters

Device

A handle to a framework device object.

DeviceState

A pointer to a driver-allocated WDF_DEVICE_STATE structure that contains the device's state information.

Return Value

None.

A bug check occurs if the driver supplies an invalid object handle.

Remarks

When a driver calls WdfDeviceSetDeviceState, the framework notifies the Plug and Play (PnP) manager that the device state has changed.

Examples

The following code example informs the PnP manager that a specified device is disabled.

WDF_DEVICE_STATE    deviceState;

WDF_DEVICE_STATE_INIT (&deviceState);
deviceState.Disabled = WdfTrue;
WdfDeviceSetDeviceState (
                         Device,
                         &deviceState
                         );
