3/26/2014

This section discusses the Windows-specific extension functions.

In This Section

• WSAAccept
  Conditionally accepts a connection based on the return value of a condition function and allows the transfer of connection data

• WSAAsyncGetHostByName
  Deprecated.

  Asynchronously retrieves information about a host that corresponds to a host name

• WSAAsyncSelect
  Requests Windows message-based notifications of network events for a socket

• WSACancelAsyncRequest
  Cancels an incomplete asynchronous operation

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

• WSACleanup
  Terminates use of the ws2.dll

• WSACloseEvent
  Closes an open event object handle

• WSAConnect
  Establishes a connection to another socket application and exchanges connect (Windows Sockets) data

• WSACreateEvent
  Creates a new event object

• WSAEnumNameSpaceProviders
  Retrieves information about available name spaces

• WSAEnumNetworkEvents
  Discovers occurrences of network events for the indicated socket, clear internal network event records, and reset event objects (optional)

• WSAEnumProtocols
  Retrieves information about available transport protocols

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

• WSAGetLastError
  Gets the error status for the last operation that failed

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

• WSAHtonl
  Converts a u_long from host byte order to network byte order

• WSAHtons
  Converts a u_short from host byte order to network byte order

• WSAIoctl
  This function allows for miscellaneous control of a socket

• WSAJoinLeaf
  This function joins a leaf node into a multipoint session, and exchanges connect data

• WSALookupServiceBegin (Windows Sockets)
  Initiates a client query that is constrained by the information contained within a WSAQUERYSET (Windows Sockets) structure. This function only returns a handle, which should be used by subsequent calls to the WSALookupServiceNext (Windows Sockets) function to get the actual results

• WSALookupServiceEnd (Windows Sockets)
  This function is called to free the handle after previous calls to WSALookupServiceBegin (Windows Sockets) and WSALookupServiceNext (Windows Sockets)

• WSALookupServiceNext (Windows Sockets)
  Deprecated.

  This function is called after obtaining a handle from a previous call to the WSALookupServiceBegin (Windows Sockets) function to retrieve the requested service information

• WSANSPIoctl
  This function enables developers to make I/O control calls to a registered namespace

• WSANtohl
  Converts a u_long from network byte order to host byte order

• WSANtohs
  Converts a u_short from network byte order to host byte order

• WSARecv
  Receives data from a connected socket

• WSARecvFrom
  Receives data on a socket and stores the source address

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

• WSASend
  Sends data on a connected socket

• WSASendTo
  Sends data to a specific destination, using overlapped I/O where applicable

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

• WSASetLastError
  Sets the error code that can be retrieved through the WSAGetLastError function

• WSASetService (Windows Sockets)
  Registers or removes from the registry a service instance within one or more name spaces

  Note

  This function is not supported for the default TCP/UDP provider. However, third parties can implement their own provider and have support for this function if they choose.

• WSASocket
  Creates a socket that is bound to a specific transport service provider

• WSAStartup
  Initiates use of ws2.dll by a process

• WSAStringToAddress
  Converts a numeric string to a sockaddr structure suitable for passing to Windows Sockets routines that take such a structure

• WSAWaitForMultipleEvents
  Waits for multiple events and returns either when one or all of the specified event objects are in the signaled state, or when the timeout interval expires
