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).
