powerChangeDone

Tells a driver when a power state change is complete.

Declaration

virtual void powerChangeDone(
 unsigned longstateNumber );

Parameters

  • stateNumber:

    The number of the state in the state array that the device has switched from.

Overview

Power management uses this method to inform a driver when a power change is completely done, when all interested parties have acknowledged the powerStateDidChangeTo call. The default implementation of this method is null; the method is meant to be overridden by subclassed power managed drivers. A driver should use this method to find out if a power change it initiated is complete.
