Sadly the Windows asynchronous (or something, I never quite got it) networking API seems very powerful. But I never found a comprehensible manual/tutorial for it.

Dr.Dobbs has had at least 2 articles on it.

I remember chatting in the fringes when nodeJS was doing their proper win32 porting and they did have some issues getting things stable due to lack of documentation but iirc got some help from MS so the libuv code should be usable as a reference for behaviours (As well as being fairly battle tested by now).

I’ve been trying to figure out the entire windows networking stack recently, particularly some more obscure parts and the docs have been pretty bad unfortunately. A lot of the higher level stuff fees really superficial and the lower level stuff it’s it own mess (all sorts of broken links and links to outdated versions in the NDIS docs).

"At first glance this seems like a great read" Agree!
