PFN_WSK_RELEASE_DATA_INDICATION_LIST callback function (wsk.h)

The WskRelease function releases a linked list of WSK_DATA_INDICATION structures that was previously retained by a WSK application.

WskRelease can be declared in two different ways, depending on the type of socket. This topic describes WskRelease for connection-oriented or listening sockets. For datagram sockets, see WskRelease (datagram sockets).

Syntax

PFN_WSK_RELEASE_DATA_INDICATION_LIST PfnWskReleaseDataIndicationList;

NTSTATUS PfnWskReleaseDataIndicationList(
  [in] PWSK_SOCKET Socket,
  [in] PWSK_DATA_INDICATION DataIndication
)
{...}

Parameters

[in] Socket

A pointer to a WSK_SOCKET structure that specifies the socket object for the socket from which the data was received.

[in] DataIndication

A pointer to the linked list of structures to be released. For this parameter, the WSK application should specify the DataIndication parameter that was passed to its WskReceiveEvent or WskReceiveFromEvent event callback function.

Return value

WskRelease returns one of the following NTSTATUS codes:

Remarks

For connection-oriented or listening sockets, a WSK application calls the WskRelease function to release a linked list of WSK_DATA_INDICATION structures that it previously retained by returning STATUS_PENDING from either its WskReceiveEvent or its WskReceiveFromEvent event callback function.

Closing a socket by calling the WskCloseSocket function does not release any outstanding retained linked lists of structures. A WSK application must release all retained linked lists of structures before the application calls the WskCloseSocket function to close the socket.
