atalk - AppleTalk protocol family


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


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.


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).


bind(2), getsockname(2), atalkd(8).

00:43 00:39 c'est barbare de draguer sur irc. Les gens convenables
devraient faire leurs déclarations dans les news. puis on fait un
AAD, puis un AAV. un bon vote pour départager les prétendants.
ensuite une charte lie les heureux époux. :)
