SOCK_REGISTER(9) Linux Networking SOCK_REGISTER(9)NAME
sock_register - add a socket protocol handler
SYNOPSIS
int sock_register(const struct net_proto_family * ops);
ARGUMENTS
ops
description of protocol
DESCRIPTION
This function is called by a protocol handler that wants to advertise its address family, and have it linked into the socket interface. The
value ops->family coresponds to the socket system call protocol family.

ATALK(4F)ATALK(4F)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).
