1/6/2010

NdisGetPacketCancelId returns the cancellation identifier assigned to a packet.

Syntax

PVOID NdisGetPacketCancelId(
  PNDIS_PACKET Packet
);

Parameters

  • Packet
    [in] Pointer to an NDIS_PACKET structure that is the descriptor for a packet.

Return Value

Returns the cancellation identifier for the specified packet.

Remarks

A protocol or intermediate driver can call NdisGetPacketCancelId to obtain the cancellation identifier for a packet.

A miniport driver calls NdisGetPacketCancelId from its MiniportCancelSendPackets function to obtain cancellation identifiers of packets in its send queue. If a packet's cancellation identifier matches the cancellation identifier passed to the miniport driver's MiniportCancelSendPackets function, the miniport driver cancels the pending transmission of the packet.
