Data Structures

The Address Block Record

The address block record defines a data structure of AddrBlock type. ADSP routines use this data type to specify the AppleTalk internet socket address of the remote connection end in the CCB. You can use NBP to get the address of an application that
is registered with NBP. See the chapter "Name-Binding Protocol (NBP)" in this book for more information. ATP functions also use this data type to specify AppleTalk internet socket addresses.

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