Everytime I start a new socket application, I always start with Beej's examples (found here: http://beej.us/guide/bgnet/). Once I have the basics, I add in sendall, rewrite the receive routine to get all of the input into one buffer as well as so some cleaning. I've started to replace some of the code with C++ in the hopes to eventually convert it into OO. Instead of doing this for the 1,000th time, I am comitting it here. Feel free to make impovements specifically around readability, performance and ease of use.

Enjoy
