This macro sets the TimeSentvalue in the out-of-band data block associated with a specified packet descriptor.
NDIS_SET_PACKET_TIME_SENT( IN PNDIS_PACKET Packet , IN ULONGLONG TimeSent );
Parameters
- Packet
- Pointer to a packet descriptor allocated by the caller for receive indications.
- TimeSent
- Specifies the system time at which the packet was transmitted
over the network from a remote node.
Remarks
Miniports can use this macro to set this time stamp in the out-of-band data block associated with a packet descriptor that they are about to indicate with the NdisMIndicateReceivePacketfunction.
All time stamps set in the NDIS_PACKET_OOB_DATAstructures associated with packets are expressed in system time units as the number of 100-nanosecond intervals since January 1, 1601.
When a protocol driver's ProtocolReceivePacketfunction is called with such an indication, it can use the NDIS_GET_PACKET_TIME_SENTmacro to retrieve the TimeSenttime stamp, using the Packetpointer that it is given on entry.
If the ProtocolReceivefunction is called with an indicated packet descriptor for which the underlying driver set the TimeSenttime stamp, ProtocolReceivecalls the NdisQueryReceiveInformationfunction to get this time stamp.
A driver that uses this macro runs at IRQL <=DISPATCH_LEVEL.
