156 @param messageArgument An argument for message, dependent on its type.
539 @discussion Registering an IOService object informs possible clients of its existance and instantiates drivers that may be used with it; <code>terminate</code> involves the opposite process of informing clients that an IOService object is no longer able to be used and will be destroyed. By default, if any client has the service open, <code>terminate</code> fails. If the <code>kIOServiceRequired</code> flag is passed however, <code>terminate</code> will be successful though further progress in the destruction of the IOService object will not proceed until the last client has closed it. The service will be made inactive immediately upon successful termination, and all its clients will be notified via their @link message message@/link method with a message of type <code>kIOMessageServiceIsTerminated</code>. Both these actions take place on the caller's thread. After the IOService object is made inactive, further matching or attach calls will fail on it. Each client has its @link stop stop@/link method called upon their close of an inactive IOService object , or on its termination if they do not have it open. After <code>stop</code>, @link detach detach@/link is called in each client. When all clients have been detached, the @link finalize finalize@/link method is called in the inactive service. The termination process is inherently asynchronous because it will be deferred until all clients have chosen to close.
648 @discussion IOService will deliver notifications of changes in state of an IOService object to registered clients. The type of notification is specified by a symbol, for example <code>gIOMatchedNotification</code> or <code>gIOTerminatedNotification</code>, and notifications will only include IOService objects that match the supplied matching dictionary. Notifications are ordered by a priority set with <code>addNotification</code>. When the notification is installed, its handler will be called with each of any currently existing IOService objects that are in the correct state (eg. registered) and match the supplied matching dictionary, avoiding races between finding preexisting and new IOService events. The notification request is identified by an instance of an IONotifier object, through which it can be enabled, disabled, or removed. <code>addNotification</code> consumes a retain count on the matching dictionary when the notification is removed.

1391 If the driver is managing the idleness determination totally on its own, the value of the <code>type</code> parameter should be <code>kIOPMSubclassPolicy</code>, and the driver should override the <code>activityTickle</code> method. The superclass IOService implementation of <code>activityTickle</code> does nothing with the <code>kIOPMSubclassPolicy</code> argument.
1393 @param type When <code>type</code> is <code>kIOPMSubclassPolicy</code>, <code>activityTickle</code> is not handled in IOService and should be intercepted by the subclass. When <code>type</code> is <code>kIOPMSuperclassPolicy1</code>, an activity flag is set and the device state is checked. If the device has been powered down, it is powered up again.
1394 @param stateNumber When <code>type</code> is <code>kIOPMSuperclassPolicy1</code>, <code>stateNumber</code> contains the desired power state ordinal for the activity. If the device is in a lower state, the superclass will switch it to this state. This is for devices that can handle some accesses in lower power states; the device is powered up only as far as it needs to be for the activity.
1395 @result When <code>type</code> is <code>kIOPMSuperclassPolicy1</code>, the superclass returns <code>true</code> if the device is currently in the state specified by <code>stateNumber</code>. If the device is in a lower state and must be powered up, the superclass returns <code>false</code>; in this case the superclass will initiate a power change to power the device up.

1497 @discussion A driver using the idleness determination provided by IOService calls its superclass with this method to set or change the idle timer period. See @link activityTickle activityTickle@/link for a description of this type of idleness determination.
