tcp-c

TCP server-client implementation in c

Server

• Socket -> setsockopt -> Bind -> Listen -> Accept -> Send/Recv <-> send/Recv[Client]

Client

• Socket -> Connect -> Listen[Socket] && send/Recv[Client]

The entire process can be broken down into following steps:

TCP Server:

1. using create(), Create TCP socket.
2. using bind(), Bind the socket to server address.
3. using listen(), put the server socket in a passive mode, where it waits for the client to approach the server to make a connection
4. using accept(), At this point, connection is established between client and server, and they are ready to transfer data.
5. Go back to Step 3.

TCP Client:

1. Create TCP socket.
2. connect newly created client socket to server.
