About the AppleTalk Utilities
The AppleTalk Utilities are a group of diverse functions, some of which allow you to obtain information about AppleTalk and the networking environment of your node
and some of which allow you change values that affect AppleTalk features.The
PGetAppleTalkInfo
function returns a wide range of information, including some information that other functions belonging to the AppleTalk Utilities also return. For example, bothPGetAppleTalkInfo
andGetNodeAddress
return the node ID and network address of the user node that is running your application. ThePGetAppleTalkInfo
function returns the node ID and the network number of
the last router from which the node that is running your application has heard; theGetBridgeAddress
function also returns the node ID of the internet router on your node's local network.
Although the AppleTalk interface does not include a function that you can use to direct AppleTalk to select a node ID from the server node range when you open AppleTalk,
- Note
- The
PGetAppleTalkInfo
function was developed and made available after theGetNodeAddress
andGetBridgeAddress
functions. Apple Computer, Inc. recommends that you use thePGetAppleTalkInfo
function to obtain addressing information for a user node or router instead of using theGetNodeAddress
andGetBridgeAddress
functions.
this chapter describes how you can do this. If your application or the application that opened AppleTalk directed AppleTalk to assign a server node ID to the node, thePGetAppleTalkInfo
function will return a flag that tells you this request was made.AppleTalk includes a feature called intranode delivery that allows two programs running on the same node to communicate with each other through the AppleTalk protocols. The AppleTalk Utilities include the
PSetSelfSend
function, which you can use to enable or disable intranode delivery. ThePGetAppleTalkInfo
function will
tell you if intranode delivery is on or off.
