readme

this gives details of the network programming

Simple threaded server example. The server provides a "chat" service
to multiple TCP clients. Anything sent by a client is forwarded to
all other clients. 

Each client is handled by a thread, the threads all share information
about the current list of clients through a set of global variables. 
Access to the global variables is restricted to a single thread at
a time using a pthread_mutex. 

There is also a thread that provides system status through stdin,stdout.

To test this server out, just run it and then use telnet to connect with
a bunch of clients. MAXCLIENTS is currently defined to be 10, which means
the server can support up to 10 clients at once.
