NAME

       atalk - AppleTalk protocol family

SYNOPSIS

       #include <sys/types.h>
       #include <netatalk/at.h>

DESCRIPTION

       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.

ADDRESSING

       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;
           u_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   coresponds   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).
