A combination of Basic information (attributes and time stamps) and Standard
information (sizes).
The resulting structure is fixed size - so, no STATUS_BUFFER_OVERFLOW stuff.
The structure is declared in NTIFS.H
IIRC it is used by the RDR/SRV pair because there is a SMB corressponding to
it exactly - the purpose is to avoid sending 2 SMBs for Basic and Standard
information over the network when 1 SMB will be enough.
