9 The AppleTalk protocol family is a collection of protocols layered
10 above the Datagram Delivery Protocol (DDP), and using AppleTalk address
11 format. The AppleTalk family may provide SOCK_STREAM (ADSP), SOCK_DGRAM
12 (DDP), SOCK_RDM (ATP), and SOCK_SEQPACKET (ASP). Currently, only DDP is
13 implemented in the kernel; ATP and ASP are implemented in user level
14 libraries; and ADSP is planned.
16 AppleTalk addresses are three byte quantities, stored in network
17 byte order. The include file
19 defines the AppleTalk address format.
21 Sockets in the AppleTalk protocol family use the following address
29 struct at_addr sat_addr;
35 The port of a socket may be set with
41 ``this node.'' The net may be

50 is sent, i.e. determined late.
52 is equivalent to opening one socket for each network interface. The
