This structure contains the fields necessary in order for the Bus driver to carry out a GetMaxSpeedBetweenDevices request.
fulFlags
Specifies the source device. Zero indicates the calling device. USE_LOCAL_NODE indicates the computer itself.
Note In Windows 7, the new 1394 bus driver returns only the speed between the local node and the device. The USE_LOCAL_NODE flag must be set in the u.GetMaxSpeedBetweenDevices.fulFlags parameter.
ulNumberOfDestinations
Specifies the number of destination devices.
hDestinationDeviceObjects
Points to an array of the device objects of the destination devices.
fulSpeed
Specifies the maximum speed returned.
