Chapter 12 - Multinode Architecture

Using Multinode Architecture

This section describes how to

• acquire a multinode (AddNode)
• receive data addressed to the multinode
• prepare to send data and then send it from the multinode (NetWrite)
• remove a multinode when you are finished with it (RemoveNode)

It also mentions the cable-range-change AppleTalk transition event that you must handle and directs you to the chapter "Link-Access Protocol (LAP) Manager" for information describing what you must do.

The routines that you use to add and remove a multinode and send data from your multinode application are not defined in the MPW interface files. To use these routines from a high-level language, you must call the Device Manager directly and specify
the routine's csCode in the parameter block. For the AddNode routine, you must issue the function as an immediate control call and define a function for this purpose. (For
an example of how to do this, see Listing 12-1 on page 12-8.) For the NetWrite and RemoveNode routines, you call the Device Manager's PBControl function. (For infor-
mation about how to do this, see "Routines" beginning on page 12-19.)

Note

AppleTalk version 57 or later must be installed on the system that is running your application if you use the multinode feature. AppleTalk version 57 is compatible with system software version 6.0.5 and later. You should include AppleTalk version 57 with any product that uses multinodes. Contact Apple's Software Licensing department for information on licensing AppleTalk.
