This code is a network app I wrote a long time ago for communicating with Yahoo and MSN before they were stopped.
It is here as an example of network code (could do with a lot of updating for later C++ constructs).
Note: I never completed this application or got it to work properly as it was primarily for play purposes and working out a simple network protocol, so I accept no liability or responsibility it not working. Use it at your own risk.
NOTE - This will never work as the protocols are no longer available. However, it is useful for a basis for CPP based network protocols, but the program itself does not work, so no point running it.
