I just encountered an undocumented value for the
u.AllocateAddressRange.fulFlags value in the Microsoft 1394 bus driver IRB
data structure, in the Windows XP DDK 1394.h file.

It is ALLOCATE_ADDRESS_FLAGS_USE_COMMON_BUFFER, with a value 0x2.

What does this mean? I can't find any documentation for it anywhere.

Thanks for any help.
