Quick clarification - Steve requested that the info level
returned be aligned to a 4 byte boundary - so the returned
values will look like :

: The reply data block looks like the following

Size              Offset                  Value
-----------------------------------------------
1 byte           0                    oplock granted flags
                                      (as returned by NTCreateX)
1 byte           1                    Must be Zero.
2 bytes          2                    Returned fnum.
2 bytes          4                    Info level returned for the
                                      opened file, or 0xFFFF if no
                                      info level returned.
2 bytes          6                    Must be zero

N bytes          8                    Optional level-dependent data.
