Data Structures

The Address Block Record

The address block record defines a data structure of AddrBlock type. You use this record type for

• the reqNodeAddr field value of the multinode parameter block to specify the preferred network number and multinode ID of the multinode that you wish to acquire when you execute the AddNode routine
• the actNodeAddr parameter block field for the AddNode routine for the .MPP driver to return the multinode address that it assigns to you
• the nodeAddr parameter block field for the RemoveNode routine to specify the address of the multinode to be removed

TYPE AddrBlock = 
PACKED RECORD
   aNet:          Integer;    {network number}
   aNode:         Byte;       {node ID}
   aSocket:       Byte;       {socket number}
END; 

Field Description

aNet

The number of the desired network to which the multinode node that you are requesting or assigned belongs.

aNode

The node ID of the multinode that you request or that MPP assigns.

aSocket

The value of this field should always be 0.
