On a more flamebaity note, I don't know why you'd even want to write something like this in C. Writing a server for one of the most prevalent network protocols on the Internet in C, in 2015, just seems like masochism.

C++ would've reduced and simplified the code substantially and there are a growing number of other fine choices these days.
