H A DIOService.h660 @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.

744 @abstract Creates a matching dictionary, or adds matching properties to an existing dictionary, that specify an IOService class match.
745 @discussion A very common matching criteria for IOService object is based on its class. <code>serviceMatching</code> creates a matching dictionary that specifies any IOService object of a class, or its subclasses. The class is specified by name, and an existing dictionary may be passed in, in which case the matching properties will be added to that dictionary rather than creating a new one.
