CdInitializeFcbFromPathEntry(
  IN  PIRP_CONTEXT IrpContext,
  IN  PFCB Fcb,
  IN  PFCB ParentFcb OPTIONAL,
  IN  PPATH_ENTRY PathEntry
  );

Routine Description:

    This routine is called to initialize an Fcb for a directory from
    the path entry.  Since we only have a starting point for the directory,
    not the length, we can only speculate on the sizes.

    The general initialization is performed in CdCreateFcb.

Arguments:

    Fcb - Newly created Fcb for this stream.

    ParentFcb - Parent Fcb for this stream.  It may not be present.

    PathEntry - PathEntry for this Fcb in the Path Table.

Return Value:

    None
