NAME
atalk - AppleTalk protocol familySYNOPSIS
#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).SEE ALSO
