_IRB_RECEIVE_PHY_PACKETS structure

Description

This structure contains the fields necessary to carry out a ReceivePhyPackets request.

Members

Flags

Specifies whether a callback should be registered or deactivated. Use REGISTER_PHY_PACKET_NOTIFICATION to register PhyPacketRoutine as the callback. Use DEREGISTER_PHY_PACKET_NOTIFICATION to deactivate any previously registered callbacks.

PhyPacketRoutine

Points to the notification routine for received PHY packets. The following prototype illustrates the notification routine:

void PhyPacketRoutine(
    __in PVOID           Context,
    __in ULONG           GenerationCount,
    __in ULARGE_INTEGER  PhyPacket
);
Term Description
Context The argument that is specified in the u.ReceivePhyPackets.PhyPacketContext parameter when the REQUEST_RECEIVE_PHY_PACKET request is sent.
GenerationCount The generation count of the bus for this PHY packet.
PhyPacket The 64-bit PHY packet that is received from the 1394 bus.

PhyPacketContext

Specifies the Context argument to be passed to the PhyPacketRoutine.
