Caloris

What is Caloris?

Caloris is a simple Win32 client library for Socket.IO, without Boost::Asio. Boost::Asio is most powerful library, but Asio's IOCP model have too many thread on client side. So, Caloris select WSAEventSelect model.

Websocket protocol

Socket.IO is a module of node.js that base on RFC6455, but modified. I was analyzed Socket.IO's TCP packet and write packet code on C/C++. See more http://rhea.pe.kr/515.

WSAEventSelect

Caloris's socket model is WSAEventSelect. This is an asynchronous I/O and very fast. I like WSAEventSelect on client side. See more [http://msdn.microsoft.com/en-us/library/windows/desktop/ms741576(v=vs.85).aspx](http://msdn.microsoft.com/en-us/library/windows/desktop/ms741576(v=vs.85).

Why Caloris?

I am developing an MMORPG. When I need community module, I select the Socket.IO. But there is not Socket.IO's C++ client that make write Caloris.
