This is an ancient winsock server, based mainly on the C++ HybridCO source (which was a great C++ reference for me). If you change the winsock part to BSD sockets (follow Beej`s guide on BSD sockets, and it won`t be hard at all, I promise) it will work on Linux based systems as well. Don`t know if anyone could use this, since those of you who don`t know C++ won`t use it, those of you who do can do this by themselves. So yeah.
The ThreadSafeVector.h contains only a class which wraps the std::vector functions using boost mutexes to ensure thread safety. Won`t post that, if you can`t do this, use a regular std::vector instead. If you can`t use std::vector then get a new hobby.
