Routines / Getting the Addresses of Your Node and Local Internet Router

GetNodeAddress

The GetNodeAddress function returns the current node ID and network number of the node on which the calling program is running.

FUNCTION GetNodeAddress (VAR myNode,myNet: Integer): OSErr; 

myNode

The node ID of the node on which your application or process is running.

myNet

The network number of the network to which the node is attached that is running your application or process. If myNet returns 0, this means that there is no internet router available. However, your application or process should call GetBridgeAddress to determine if there are router-like services available to that node.

DESCRIPTION

The GetNodeAddress function returns the address of a node on a network. If the network is not an extended network, the network number that GetNodeAddress returns is 0. Note that even if GetNodeAddress returns a network number of 0, there may be a router service on the local network. For example, a node can be on a network whose network number is 0 and be connected to a remote network through Apple Remote Access (ARA).

If the .MPP driver is not installed, the GetNodeAddress function returns a function result of noMPPErr. To install the .MPP driver, open it using the Device Manager's OpenDriver function or the MPPOpen function.

ASSEMBLY-LANGUAGE INFORMATION
