NDIS_GET_PACKET_TIME_TO_SEND returns the TimeToSend value from the out-of-band data block associated with a given packet descriptor.

  _In_ PNDIS_PACKET Packet
);

Parameters

Packet [in]
Pointer to a packet descriptor.

Return value

NDIS_GET_PACKET_TIME_TO_SEND returns the timestamp, if any, set by the protocol driver before passing the Packet in an array to NdisSendPackets or as a parameter to NdisSend.

Remarks

The MiniportSendPackets or MiniportSend function of an underlying NIC driver might use NDIS_GET_PACKET_TIME_TO_SEND to determine when a given packet should be transmitted over the network.

All timestamps set in the NDIS_PACKET_OOB_DATA blocks associated with packets are expressed in system time units as the number of 100-nanosecond intervals since January 1, 1601.
