ATALK(4)		Netatalk AFP Fileserver	Manual		      ATALK(4)

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, DDP is  im-
       plemented  in  the kernel; ATP and ASP are implemented in Netatalk user
       level libraries.

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;
		  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.	deter-
       mined 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).
