TCP-Connection

A simple client-server application with I/O multiplexing.
This is just an example of C socket programming.

First you have to start the server with either make debug_server or make run_server.
The server will be binded to the loopback address 127.0.0.1 and port 50000.
Then you can start the clients with either make debug_client or make run_client.
To use the debug mode you need to have valgrind previously installed.

Server interaction

To keep it simple, the only server command is exit, which closes the server and all the
connected clients. Please note that the server might go into a TIME_WAIT state if a client
closes after the server, in which case you have to wait a few seconds before attempting to
restart the server. You will observe this behaviour upon receiving the Address is already in use
message.

Client interaction

The command to close a client is disconnect.
In order to send a message to the server, you have to issue the cmd command. Then, you enter the
message you wish to send to the server.
