WdfDeviceResumeIdle method

[Applies to KMDF and UMDF]

The WdfDeviceResumeIdle method informs the framework that the specified device is not in use and can be placed in a device low-power state if it remains idle.

Syntax


VOID WdfDeviceResumeIdle(
  [in]  WDFDEVICE Device
);

Parameters

Device [in]

A handle to a framework device object.

Return value

None.

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

Remarks

Every call to WdfDeviceStopIdle must eventually be followed by a call to WdfDeviceResumeIdle, or else the device will never return to a low-power state if it again becomes idle.

Examples

The following code example informs the framework that the specified device is not in use and can be placed in a device low-power state if it remains idle.


WdfDeviceResumeIdle(device);
