  21 /*  FUNCTION
  22         Initializes the given IFFHandle to be a DOS stream. It installs a
  23         "custom" stream handler (via InitIFF) to handle DOS streams.
  24         The iff_Stream field of the iffhandle will still need
  25         to be initializes with a filehandle struct as returned from
  26         dos.library/Open(). The iff_Flags may be changed to
  27         change the seekability of the stream after this function is called,
  28         but before OpenIFF() is called. Seekability for dos files
  29         default to IFFF_RSEEK (random seekable).
