The tcpip.so library
The routines in this dynamic library create addresses from the
hosts(4tcp)
TCP/IP package.
The hosts file contains the machine's IP address as the first field
followed by any number of machine names separated by white space.
For example:
#IP address machine name(s) (optional comment)
#
192.11.108.01 bilbo
192.11.108.16 elvis # Located at Graceland
192.11.103.2 weeble wombat
The services
file contains three fields:
``service name'', ``port/protocol'' (with one of two protocol
specifications either ``tcp'' or ``udp''),
and ``aliases''.
For example:
#service name port/protocol aliases
#
netstat 15/tcp
netstat 15/udp
time 37/tcp mail
time 37/udp mail
nntp 119/tcp usenet readnews untp
For an application to use this library to request
the address of a service on a particular
host, the host name must appear in the
/etc/hosts file and the service name must appear in
the /etc/services file.
If one or the other does not appear,
an error will be returned
by the name-to-address mapping routines.
