This section discusses the Winsock SPI functions.

In This Section

• NSPCleanup
  Terminates the use of a particular Windows Sockets name space service provider

• NSPGetServiceClassInfo
  Retrieves all the pertinent class information (schema) pertaining to the name-space provider

• NSPInstallServiceClass
  Registers service class schema within the name-space providers

• NSPLookupServiceBegin
  Initiates a client query that is constrained by the information contained within a WSAQUERYSET (Windows Sockets) structure

• NSPLookupServiceEnd
  Frees the handle after previous calls to NSPLookupServiceBegin and NSPLookupServiceNext

• NSPLookupServiceNext
  Called after obtaining a handle from a previous call to NSPLookupServiceBegin in order to retrieve the requested service information

• NSPRemoveServiceClass
  Permanently removes a specified service class from the name space

• NSPSetService
  This function registers or deregisters a service instance within a name space

• NSPStartup
  Retrieves the dynamic information about a provider, such as the list of the DLL entry points

• WPUCloseEvent
  Closes an open event object handle

• WPUCloseSocketHandle
  Closes an existing socket handle

• WPUCompleteOverlappedRequest
  Performs overlapped I/O completion notification for overlapped I/O operations

• WPUCreateEvent
  Creates a new event object

• WPUCreateSocketHandle
  Creates a new socket handle

• WPUFDIsSet
  Checks the membership of the specified socket handle

• WPUGetProviderPath
  Retrieves the DLL path for the specified provider

• WPUQueryBlockingCallback
  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 Compact. However, third parties can implement their own provider and have support for this function if they choose.

• WPUQuerySocketHandleContext
  Queries the context value associated with the specified socket handle

• WPUResetEvent
  Resets the state of the specified event object to nonsignaled

• WPUSetEvent
  Sets the state of the specified event object to signaled

• WSCDeinstallProvider
  Removes the specified transport provider from the system configuration database

• WSCEnumProtocols
  Retrieves information about available transport protocols

• WSCInstallNameSpace
  Installs a name-space provider

• WSCInstallProvider
  Installs the specified transport provider into the system configuration database

• WSCUnInstallNameSpace
  Uninstalls the indicated name-space provider

• WSPAccept
  Conditionally accepts a connection based on the return value of a condition function

• WSPAddressToString
  Converts all parts of a sockaddr structure into a human readable-numeric string representation of the address

• WSPAsyncSelect
  Requests Windows message-based event notification of network events for a socket

• WSPBind
  Associates a local address (that is, name) with a socket

• WSPCleanup
  Terminates use of the Windows Sockets service provider

• WSPCloseSocket
  Closes a socket

• WSPConnect
  Establishes a connection to a peer, and exchanges connect data

• WSPDuplicateSocket
  Returns a structure that can be used to create a new socket descriptor for a shared socket

• WSPEnumNetworkEvents
  Reports occurrences of network events for the indicated socket

• WSPEventSelect
  Specifies an event object to be associated with the supplied set of network events

• WSPGetOverlappedResult
  Returns the results of an overlapped operation on the specified socket

• WSPGetPeerName
  Gets the address of the peer to which a socket is connected

• WSPGetSockName
  Gets the local name for a socket

• WSPGetSockOpt
  Retrieves a socket option

• WSPIoctl
  Controls the mode of a socket

• WSPJoinLeaf
  Joins a leaf node into a multipoint session, and exchanges connect data

• WSPListen
  Establishes a socket to listen for incoming connections

• WSPRecv
  Receives data on a socket

• WSPRecvDisconnect
  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 Compact. However, third parties can implement their own provider and have support for this function if they choose.

• WSPRecvFrom
  Receives a datagram and stores the source address

• WSPSelect
  Determines the status of one or more sockets

• WSPSend
  Sends data on a connected socket

• WSPSendDisconnect
  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 Compact. However, third parties can implement their own provider and have support for this function if they choose.

• WSPSendTo
  Sends data to a specific destination using overlapped I/O

• WSPSetSockOpt
  Sets a socket option

• WSPShutdown
  Disables sends and/or receives on a socket

• WSPSocket
  Creates a socket

• WSPStartup
  Initiates use of a Windows Sockets service provider by a client

• WSPStringToAddress
  Converts a human-readable numeric string to a socket address structure (sockaddr) suitable to passing to Windows Sockets routines that take such a structure
