atalk - AppleTalk protocol family

       AppleTalk addresses are three byte quantities, stored in network byte order. The include file
       <netatalk/at.h> defines the AppleTalk address format.

       Sockets in the AppleTalk protocol family use the following address structure:

           struct sockaddr_at {
               short sat_family;
               unsigned char sat_port;
               struct at_addr sat_addr;
               char sat_zero[ 8 ];
           };

       The port of a socket may be set with bind(2). The node for bind must always be ATADDR_ANYNODE: ``this
       node.'' The net may be ATADDR_ANYNET or ATADDR_LATENET.  ATADDR_ANYNET corresponds to the machine's
       ``primary'' address (the first configured).  ATADDR_LATENET causes the address in outgoing packets to be
       determined when a packet is sent, i.e. determined late.  ATADDR_LATENET is equivalent to opening one
       socket for each network interface. The port of a socket and either the primary address or ATADDR_LATENET
       are returned with getsockname(2).

       The AppleTalk protocol family is a collection of protocols layered above the Datagram Delivery Protocol
       (DDP), and using AppleTalk address format. The AppleTalk family may provide SOCK_STREAM (ADSP),
       SOCK_DGRAM (DDP), SOCK_RDM (ATP), and SOCK_SEQPACKET (ASP). Currently, only DDP is implemented in the
       kernel; ATP and ASP are implemented in user level libraries; and ADSP is planned.
