                      5: .SH SYNOPSIS
                      6: .B #include <sys/types.h>

                     19: ..
                     20: The Internet protocol family is a collection of protocols
                     21: layered atop the
                     22: .I Internet Protocol
                     23: (IP) transport layer, and utilizing the Internet address format.
                     24: The Internet family provides protocol support for the
                     25: SOCK_STREAM, SOCK_DGRAM, and SOCK_RAW socket types; the
                     26: SOCK_RAW interface provides access to the IP protocol.
                     27: .SH ADDRESSING
                     28: Internet addresses are four byte quantities, stored in
                     29: network standard format (on the VAX these are word and byte
                     30: reversed).  The include file
                     31: .RI < netinet/in.h >
                     32: defines this address
                     33: as a discriminated union.
                     34: .PP
                     35: Sockets bound to the Internet protocol family utilize
                     36: the following addressing structure,
                     37: .sp 1
                     38: .nf
                     39: ._f
                     40: struct sockaddr_in {
                     41:        short   sin_family;
                     42:        u_short sin_port;
                     43:        struct  in_addr sin_addr;
                     44:        char    sin_zero[8];
                     45: };
                     46: .sp 1
                     47: .fi
                     48: Sockets may be created with the address INADDR_ANY
                     49: to effect \*(lqwildcard\*(rq matching on incoming messages. 
                     50: .SH PROTOCOLS
                     51: The Internet protocol family is comprised of
                     52: the IP transport protocol, Internet Control
                     53: Message Protocol (ICMP), Transmission Control
                     54: Protocol (TCP), and User Datagram Protocol (UDP).
                     55: TCP is used to support the SOCK_STREAM
                     56: abstraction while UDP is used to support the SOCK_DGRAM
                     57: abstraction.  A raw interface to IP is available
                     58: by creating an Internet socket of type SOCK_RAW.
                     59: The ICMP message protocol is not directly accessible.
                     60: .SH SEE ALSO
                     61: tcp(4P), udp(4P), ip(4P)
                     62: .SH CAVEAT
                     63: The Internet protocol support is subject to change as
                     64: the Internet protocols develop.  Users should not depend
                     65: on details of the current implementation, but rather
                     66: the services exported.
