Experiment 6.2

Chapter 6

6.3

6.4

First, the answer to the question posed in Experiment 6.1. In client.c you find the following code fragment:
n=recv(...)
while(n>0) {

write(...)
n=recv(...)

The client is waiting for more data. It will not learn that there is no more data until the server terminates the TCP connection. So when you modify this code to get a chat server and client, you must do what was done in the starter code in chapter 5. You must test for a \n character.
Note that there is a forever loop in server.c which allows for multiple connections. You must put your own loop inside this one.
