Microsoft Windows-specific Extension Functions

The 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.

WSAAccept1	An extended version of accept which allows for conditional acceptance and socket grouping.
WSAAsyncGetHostByAddr2 WSAAsyncGetHostByName2 WSAAsyncGetProtoByName2 WSAAsyncGetProtoByNumber2 WSAAsyncGetServByName2 WSAAsyncGetServByPort2	A set of functions which provide asynchronous versions of the standard Berkeley getXbyY functions. For example, the WSAAsyncGetHostByName function provides an asynchronous message based implementation of the standard Berkeley gethostbyname function.
WSAAsyncSelect	Perform asynchronous version of select
WSACancelAsyncRequest2	Cancel an outstanding instance of a WSAAsyncGetXByY function.
WSACleanup	Sign off from the underlying Windows Sockets DLL.
WSACloseEvent	Destroys an event object.
WSAConnect1	An extended version of connect which allows for exchange of connect data and QOS specification.
WSACreateEvent	Creates an event object.
WSADuplicateSocket	Allow an underlying socket to be shared by creating a virtual socket.
WSAEnumNetworkEvents	Discover occurrences of network events.
WSAEnumProtocols	Retrieve information about each available protocol.
WSAEventSelect	Associate network events with an event object.
WSAGetLastError	Obtain details of last Windows Sockets error
WSAGetOverlappedResult	Get completion status of overlapped operation.
WSAGetQOSByName	Supply QOS parameters based on a well-known service name.
WSAHtonl	Extended version of htonl
WSAHtons	Extended version of htons
WSAIoctl1	Overlapped-capable version of ioctl
WSAJoinLeaf1	Add a multipoint leaf to a multipoint session
WSANtohl	Extended version of ntohl
WSANtohs	Extended version of ntohs
WSARecv1	An extended version of recv which accommodates scatter/gather I/O, overlapped sockets and provides the flags parameter as IN OUT
WSARecvFrom1	An extended version of recvfrom which accommodates scatter/gather I/O, overlapped sockets and provides the flags parameter as IN OUT
WSAResetEvent	Resets an event object.
WSASend1	An extended version of send which accommodates scatter/gather I/O and overlapped sockets
WSASendTo1	An extended version of sendto which accommodates scatter/gather I/O and overlapped sockets
WSASetEvent	Sets an event object.
WSASetLastError	Set the error to be returned by a subsequent WSAGetLastError
WSASocket	An extended version of socket which takes a WSAPROTOCOL_INFO struct as input and allows overlapped sockets to be created. Also allows socket groups to be formed.
WSAStartup	Initialize the underlying Windows Sockets DLL.
WSAWaitForMultipleEvents1	Blocks on multiple event objects.

The routine can block if acting on a blocking socket.
The routine is always realized by the name resolution provider associated with the default TCP/IP service provider, if any.

    Nostalgia .Net     .Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native.
