NdisTerminateOffload function (ndischimney.h)

[The TCP chimney offload feature is deprecated and should not be used.]

A protocol driver or intermediate driver calls the NdisTerminateOffload function to terminate the offload of one or more state objects

Syntax

void NdisTerminateOffload(
  [in]      IN NDIS_HANDLE                           NdisBindingHandle,
  [in, out] IN OUT PNDIS_PROTOCOL_OFFLOAD_BLOCK_LIST OffloadBlockList
);

Parameters

[in] NdisBindingHandle

The handle that NDIS provided at the NdisBindingHandle parameter of NdisOpenAdapterEx. This handle identifies the binding between the caller and the underlying intermediate driver or offload target.

[in, out] OffloadBlockList

A pointer to an NDIS_PROTOCOL_OFFLOAD_BLOCK_LIST structure that can be a stand-alone structure or the root of a linked list of such structures. These structures identify the offloaded state objects that are being terminated.

Return value

None

Remarks

An intermediate driver calls the NdisTerminateOffload function to propagate a terminate offload operation that was initiated by the host stack. For more information, see Propagating State-Manipulation Operations.

From the NDIS_MINIPORT_OFFLOAD_BLOCK_LIST structure that was passed to its MiniportTerminateOffload function, the intermediate driver constructs an NDIS_PROTOCOL_OFFLOAD_BLOCK_LIST structure. For more information, see Reusing an NDIS_MINIPORT_OFFLOAD_BLOCK_LIST Structure. The intermediate driver passes a pointer (the OffloadBlockList parameter) to this NDIS_PROTOCOL_OFFLOAD_BLOCK_LIST structure when calling the NdisTerminateOffload function.
