Microsoft Windows-specific Extension FunctionsThe Windows Sockets specification provides a number of extensions to the standard set of Berkeley Sockets routines. Principally, these extended functions allow message or function-based, asynchronous access to network events, as well as enable overlapped I/O. While use of this extended API set is not mandatory for socket-based programming (with the exception of WSAStartup and WSACleanup), it is recommended for conformance with the Microsoft Windows programming paradigm. For features introduced in Windows Sockets 2, please see New Concepts, Additions and Changes for Windows Sockets 2.
||An extended version of accept which allows for conditional acceptance and

Berkeley getXbyY functions. For example, the WSAAsyncGetHostByName function provides
an asynchronous message based implementation of the standard Berkeley
