The Xceed Winsock Library is a COM / ActiveX wrapper library for the industry standard Winsock 2. It allows you to easily write fast, scalable networking code for applications destined to run on Windows 95, 98, NT and 2000.
The Xceed Winsock Library is designed to offer all the flexibility provided by the Winsock 2 API, including support for protocol independence, quality of service and multicast, while offering a simplified object model and a built-in multithreaded low-level I/O engine. The low-level engine uses threads efficiently and takes advantage of Winsock 2 features such as overlapped I/O and completion ports (when available) so your applications can handle large loads without overtaxing your server(s).
