Using the LAP Manager
This section describes how you can use the LAP Manager's AppleTalk Transition Queue. Then it describes how to attach and detach protocol handlers for 802.2 Type 1 data packets using theL802AttachandL802Detachroutines.To use the AppleTalk Transition Queue, you add an entry for your application that contains a pointer to a transition event handler routine that you must provide to receive notification of transitions and to perform any additional processing that you want to perform in reaction to the transition.
After you add your entry, the LAP Manager will call your transition event handler routine to notify you that an AppleTalk transition either is about to occur or has occurred. The description of how to use the AppleTalk Transition Queue includes
- how to determine if the LAP Manager is installed on the node running your application
- how to add an entry to the AppleTalk Transition Queue
- how to write the routine that you must provide that the LAP Manager calls to notify you of the transition
- how to handle each of the standard AppleTalk transitions that can occur and about which your routine will be notified
- how to handle developer-defined transitions
- how to define your own transition events
