Testing instructions

1. compile the server code gcc server.c -o server -pthread
2. compile the client code gcc client.c -o client -pthread
3. Run server ./server <port number>. Eg: ./server 8089
4. Run the client in a different terminal. ./client <server> <port>. Eg: ./client localhost 8089
5. Run any number of clients in different terminals
6. Send messages to user in the format <userid> <Message>. Eg: 1 hello world

Code tested on an ubuntu 10.04 LTS machine with gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3

Usage

A message can be sent from peer to peer in the format '@ Message' It is assumed now that the entered peed id is valid integer. A '*' will enable users to broadcast message to all logged in users at the same given time. Sample message @3 Hello world :) Clients use a multi threaded approach to recieve and send messages the same time. A thread runs listening to the socket and one to stdin. This enables concurrent chat between multiple users.
