  operator void* () const;
 
  Remarks
 
  An operator that converts a stream to a pointer that can be compared to
  0. The conversion returns 0 if either failbit or badbit is set in the
  stream's error state. See ◄rdstate► for a description of the error state
  masks. A nonzero pointer is not meant to be dereferenced.
