Winsock SPI Functions (Windows Embedded CE 6.0)

1/6/2010

The following table shows the Winsock SPI functions with a description of the purpose of each.

Programming element	Description
NSPCleanup	This function terminates the use of a particular Windows Sockets name space service provider.
NSPGetServiceClassInfo	This function retrieves all the pertinent class information (schema) pertaining to the name-space provider.
NSPInstallServiceClass	This function registers service class schema within the name-space providers.
NSPLookupServiceBegin	This function initiates a client query that is constrained by the information contained within a WSAQUERYSET (Windows Sockets) structure.
NSPLookupServiceEnd	This function is called to free the handle after previous calls to NSPLookupServiceBegin and NSPLookupServiceNext.
NSPLookupServiceNext	This function is called after obtaining a handle from a previous call to NSPLookupServiceBegin in order to retrieve the requested service information.
NSPRemoveServiceClass	This function permanently removes a specified service class from the name space.
NSPSetService	This function registers or deregisters a service instance within a name space.
NSPStartup	This function retrieves the dynamic information about a provider, such as the list of the DLL entry points.
WPUCloseEvent	This function closes an open event object handle.
WPUCloseSocketHandle	This function closes an existing socket handle.
WPUCompleteOverlappedRequest	This function performs overlapped I/O completion notification for overlapped I/O operations.
WPUCreateEvent	This function creates a new event object.
WPUCreateSocketHandle	This function creates a new socket handle.
WPUFDIsSet	This function checks the membership of the specified socket handle.
WPUGetProviderPath	This function retrieves the DLL path for the specified provider.
WPUQueryBlockingCallback	This function returns a pointer to a callback function the service provider should invoke periodically while servicing blocking operations. Note: This function is not supported for the default TCP/UDP provider in Windows Embedded CE. However, third parties can implement their own provider and have support for this function if they choose.
WPUQuerySocketHandleContext	This function queries the context value associated with the specified socket handle.
WPUResetEvent	This function resets the state of the specified event object to nonsignaled.
WPUSetEvent	This function sets the state of the specified event object to signaled.
WSCDeinstallProvider	This function removes the specified transport provider from the system configuration database.
WSCEnumProtocols	This function retrieves information about available transport protocols.
WSCInstallNameSpace	This function installs a name-space provider.
WSCInstallProvider	This function installs the specified transport provider into the system configuration database.
WSCUnInstallNameSpace	This function uninstalls the indicated name-space provider.
WSPAccept	This function conditionally accepts a connection based on the return value of a condition function.
WSPAddressToString	This function converts all parts of a sockaddr structure into a human readable–numeric string representation of the address.
WSPAsyncSelect	This function requests Windows message-based event notification of network events for a socket.
WSPBind	This function associates a local address (that is, name) with a socket.
WSPCleanup	This function terminates use of the Windows Sockets service provider.
WSPCloseSocket	This function closes a socket.
WSPConnect	This function establishes a connection to a peer, and exchanges connect data.
WSPDuplicateSocket	This function returns a structure that can be used to create a new socket descriptor for a shared socket.
WSPEnumNetworkEvents	This function reports occurrences of network events for the indicated socket.
WSPEventSelect	This function specifies an event object to be associated with the supplied set of network events.
WSPGetOverlappedResult	This function returns the results of an overlapped operation on the specified socket.
WSPEnumNetworkEvents	This function reports occurrences of network events for the indicated socket.
WSPEventSelect	This function specifies an event object to be associated with the supplied set of network events.
WSPGetOverlappedResult	This function returns the results of an overlapped operation on the specified socket.
WSPGetPeerName	This function gets the address of the peer to which a socket is connected.
WSPGetSockName	This function gets the local name for a socket.
WSPGetSockOpt	This function retrieves a socket option.
WSPIoctl	This function controls the mode of a socket.
WSPJoinLeaf	This function joins a leaf node into a multipoint session, and exchanges connect data.
WSPListen	This function establishes a socket to listen for incoming connections.
WSPRecv	This function receives data on a socket.
WSPRecvDisconnect	This function terminates reception on a socket and retrieves the disconnect data, if the socket is connection oriented. Note: This function is not supported for the default TCP/UDP provider in Windows Embedded CE. However, third parties can implement their own provider and have support for this function if they choose.
WSPRecvFrom	This function receives a datagram and stores the source address.
WSPSelect	This function determines the status of one or more sockets.
WSPSend	This function sends data on a connected socket.
WSPSendDisconnect	This function initiates termination of the connection for the socket and sends disconnect data. Note: This function is not supported for the default TCP/UDP provider in Windows Embedded CE. However, third parties can implement their own provider and have support for this function if they choose.
WSPSendTo	This function sends data to a specific destination using overlapped I/O.
WSPSetSockOpt	This function sets a socket option.
WSPShutdown	This function disables sends and/or receives on a socket.
WSPSocket	This function creates a socket.
WSPStartup	This function initiates use of a Windows Sockets service provider by a client.
WSPStringToAddress	This function converts a human-readable numeric string to a socket address structure (sockaddr) suitable to passing to Windows Sockets routines that take such a structure.
