acknowledgeSetPowerState
Acknowledges the belated completion of a driver’s setPowerState power state change.
Declaration
IOReturn acknowledgeSetPowerState(void);Discussion
After power management instructs a driver to change its state by calling setPowerState, that driver must acknowledge the change when its device has completed its transition. The acknowledgement may be immediate, with a return code from setPowerState, or delayed, with this call to acknowledgeSetPowerState. Any driver that doesn’t return kIOPMAckImplied from its setPowerState implementation must later call acknowledgeSetPowerState.
