  17.      _uuuu_nnnn_gggg_eeee_tttt_wwww_cccc inserts the _wwww_cccc_hhhh_aaaa_rrrr______tttt character _c into the buffer associated with
  18.      the input stream.  That character, _c, will be returned by the next _gggg_eeee_tttt_wwww_cccc
  19.      call on that stream.  _uuuu_nnnn_gggg_eeee_tttt_wwww_cccc returns _c.
  20.  
  21.      One character of pushback is guaranteed, provided something has already
  22.      been read from the stream and the stream is actually buffered.
  23.  
  24.      If _c equals _((((_wwww_cccc_hhhh_aaaa_rrrr______tttt_))))_EEEE_OOOO_FFFF, _uuuu_nnnn_gggg_eeee_tttt_wwww_cccc does nothing to the buffer and returns
  25.      _WWWW_EEEE_OOOO_FFFF.
  26.  
  27.      _ffff_ssss_eeee_eeee_kkkk erases all memory of inserted characters.
