 16.11.1 `inetd' Servers
 -----------------------
 
 Writing a server program to be run by `inetd' is very simple.  Each time
 someone requests a connection to the appropriate port, a new server
 process starts.  The connection already exists at this time; the socket
 is available as the standard input descriptor and as the standard
 output descriptor (descriptors 0 and 1) in the server process.  Thus
 the server program can begin reading and writing data right away.
 Often the program needs only the ordinary I/O facilities; in fact, a
 general-purpose filter program that knows nothing about sockets can
 work as a byte stream server run by `inetd'.
 
    You can also use `inetd' for servers that use connectionless
 communication styles.  For these servers, `inetd' does not try to accept
 a connection since no connection is possible.  It just starts the
 server program, which can read the incoming datagram packet from
 descriptor 0.  The server program can handle one request and then exit,
 or you can choose to write it to keep reading more requests until no
 more arrive, and then exit.  You must specify which of these two
 techniques the server uses when you configure `inetd'.
