CS87 Lab 2: Part2 Sample Output

This example shows the Part2 server and 3 client's connected to a chat session. The clients can initiate the MSG protocol at any time. The server on receipt of a message, forwards it to all clients currently in the chat; the server is not a participant in the chat. Clients can join and leave the chat at any time.

Note that the server sends each client's message to the others with the client's name as a prefix: "mo: hello?". Also note that the prompt printing ($:) on a client can get oddly interleaved with the output of messages from other clients. You are not required to fix this oddness, but if you want to try to make the client side look better, one way is to use ascii escape codes to print the messages from other clients in a different font color(s) so that it is easier to differentiate a client's input and other's output. For some examples, see: ascii escape codes. You could also try something more elaborate using ncurses (see: cool C libraries for some links to ncurses). One idea is to use ncurses to split the screen in half with the client program's input (stdin) in the bottom half, and the program's output (stdout) in the top.
