H A DIOService.h1400 /*! @function acknowledgeSetPowerState
1402 @discussion After power management instructs a driver to change its state via @link setPowerState setPowerState@/link, that driver must acknowledge the change when its device has completed its transition. The acknowledgement may be immediate, via a return code from <code>setPowerState</code>, or delayed, via this call to <code>acknowledgeSetPowerState</code>.
1403 Any driver that does not return <code>kIOPMAckImplied</code> from its <code>setPowerState</code> implementation must later call <code>acknowledgeSetPowerState</code>.
1407 IOReturn acknowledgeSetPowerState( void );
1603 @result The driver must return <code>IOPMAckImplied</code> if it has complied with the request when it returns. Otherwise if it has started the process of changing power state but not finished it, the driver should return a number of microseconds which is an upper limit of the time it will need to finish. Then, when it has completed the power switch, it should call @link acknowledgeSetPowerState acknowledgeSetPowerState@/link. */
