[Applies to UMDF 1.x only]
The OnD0Exit method notifies a driver when a device exits the D0 power state so that the driver can perform necessary operations, such as disabling the device.
- pWdfDevice [in]
A pointer to the IWDFDevice interface for the device object of the device that exits the D0 power state.
- newState [in]
A WDF_POWER_DEVICE_STATE-typed value that identifies the new power state that the device is set to after it exits the D0 power state.
If the OnD0Exit callback method encounters no errors, it must return S_OK or another status code for which SUCCEEDED(status) equals TRUE. Otherwise, it must return a status code for which SUCCEEDED(status) equals FALSE. HRESULT error codes are defined in Winerror.h.
