 unsigned longnewLevel );

Parameters

  • type:

  • newLevel:

    The aggressiveness factor's new value.

Return Value

IOPMNoErr.

Overview

Implement setAggressiveness to receive a notification when an "aggressiveness Aggressiveness factors are a loose set of power management variables that contain values for system sleep timeout, display sleep timeout, whether the system is on battery or AC, and other power management features. There are several aggressiveness factors that can be broadcast and a driver may take action on whichever factors apply to it. A driver that has joined the power plane via joinPMtree will receive setAgressiveness calls when aggressiveness factors change. A driver may override this call if it needs to do something with the new factor (such as change its idle timeout). If overridden, the driver must call its superclass's setAgressiveness method in its own setAgressiveness implementation. Most drivers do not need to implement setAgressiveness.
