Allows you to access the complete Winsock 2 networking API. The Xceed Winsock Library offers all the flexibility provided by the Winsock-2 API, including support for protocol independence, quality of service, and multicast, while offering an easy to use object model and a built-in multi-threaded 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 servers. The library's functionality can be accessed through a custom COM interface which offers minimal overhead and maximum flexibility, or through an OLE automation COM interface designed to make writing efficient network code extremely easy and straightforward. Multiple types of COM interfaces are provided, allowing efficient use of the library by a wide variety of languages, including Visual Basic, Delphi, Visual C++, and VBScript. The Xceed Winsock Library allows developers to use any Winsock 2 protocol.
