// This file (along with its corresponding .cpp) defines a very thin platform abstraction layer for the use of
// networking sockets. Thankfully the underlying APIs on Windows and Linux are very similar so not much conversion
// is needed (typically just forwarding the parameters to a differently named function).
// Some of the APIs are in fact completely identical and so no forwarding function is needed.
