Update of /cvsroot/plib/plib/examples/src/net/client_server
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv7848/plib/examples/src/net/client_server

Modified Files:
	net_udp_client.cxx net_udp_server.cxx 
Added Files:
	README 
Log Message:
Cleaned up the network library - did some improvements to the client/server
example programs so that they'll actually work when you run them!!



--- NEW FILE: README ---

This example demonstrates a simple one-way communication path
between a client and a server.

It uses UDP protocol - which is unreliable but fast - don't
use it for messages that utterly must get there!

The client program can be told to send to the server on any port number of
any host computer - by default it uses 'localhost'.

The server program can be told to listen out on any port number
and to either listen to just one specific client - or to accept
messages from any client.

Usage:

    net_udp_client [-p port] [servername]
    net_udp_server [-p port] [clientname]

The default for the client is to use port 5501 on 'localhost'.
The default to the server is to listen on port 5501 and to allow anyone
to send to it.
