That's a rather loaded question, since you have architectural design decisions
to make as well. There's plenty of TCP client code samples available for the
connection part, as well as forking & threading server samples as well. But
before you even go through that trouble you really need to sit down and decide
on the application protocol, transaction steps, fault tolerance, etc.
Definitely flowchart this one before coding.
