EVT_PACKET_QUEUE_CANCEL callback function (netpacketqueue.h)

The EvtPacketQueueCancel callback function is implemented by the client driver to handle operations that must be performed before a packet queue is deleted.

Syntax

EVT_PACKET_QUEUE_CANCEL EvtPacketQueueCancel;

void EvtPacketQueueCancel(
  [_In_] NETPACKETQUEUE PacketQueue
)
{...}

Parameters

[_In_] PacketQueue

A handle to a packet queue.

Return value

None

Remarks

Register this callback function in your EVT_NET_ADAPTER_CREATE_TX(RX)QUEUE callback. Set the appropriate member of a NET_PACKET_QUEUE_CONFIG structure when you are initializing the structure with NET_PACKET_QUEUE_CONFIG_INIT, then call NetTx(Rx)QueueCreate.

NetAdapterCx serializes this callback function along with the packet queue's EVT_PACKET_QUEUE_ADVANCE and EVT_PACKET_QUEUE_ADVANCE callback functions.

For more info and a diagram showing the NetAdapterCx data path polling model, see Transmit and receive queues.
