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.
