NdisCopySendNetBufferListInfo function (ndis/nblapi.h)

Intermediate drivers call the NdisCopySendNetBufferListInfo function to copy the NET_BUFFER_LIST information in a transmit NET_BUFFER_LIST structure.

Syntax

NDIS_EXPORTED_ROUTINE VOID NdisCopySendNetBufferListInfo(
  [in] NET_BUFFER_LIST       *DestNetBufferList,
  [in] NET_BUFFER_LIST const *SrcNetBufferList
);

Parameters

[in] DestNetBufferList

A pointer to the destination NET_BUFFER_LIST structure.

[in] SrcNetBufferList

A pointer to the source NET_BUFFER_LIST structure.

Return value

None

Remarks

When an intermediate driver or filter driver receives a transmit request from an overlying driver, it can, for example, clone the NET_BUFFER_LIST structure or allocate a new structure to propagate the request to underlying drivers. The driver should use NdisCopySendNetBufferListInfo to copy the NET_BUFFER_LIST information, including private NDIS information, to the new structure.

To copy the NET_BUFFER_LIST information on the receive path, use the NdisCopyReceiveNetBufferListInfo function.
