    IN NDIS_HANDLE  NdisFilterHandle,
    IN PVOID  CancelId
    );

Parameters

  • NdisFilterHandle
    The NDIS handle that identifies this filter module. NDIS passed the handle to the filter driver in a call to the FilterAttach function.
  • CancelId
    The cancellation identifier. This identifier specifies the network data for the transmission that is being canceled.

Return Value

None

Remarks

A filter driver can cancel the send requests that it originates or pass on the cancellation requests from overlying drivers. To cancel a send request from an overlying driver, NDIS calls the filter drivers FilterCancelSendNetBufferLists function.

A filter driver can call the NDIS_SET_NET_BUFFER_LIST_CANCEL_ID macro to mark NET_BUFFER_LIST structures that it originates and passes down to lower-level drivers for transmission. The NDIS_SET_NET_BUFFER_LIST_CANCEL_ID macro marks the specified packet with a cancellation identifier.

NdisFCancelSendNetBufferLists cancels the transmission of all data that is marked with the specified cancellation identifier.

NDIS returns canceled send data that the filter driver originated to the FilterSendNetBufferListsComplete function. The completion status of canceled requests is NDIS_STATUS_SEND_ABORTED.
