  48 .BR fcvt_r (),
  49 .BR qecvt_r ()
  50 and
  51 .BR qfcvt_r ()
  52 are identical to
  53 .BR ecvt ,
  54 .BR fcvt ,
  55 .BR qecvt
  56 and
  57 .BR qfcvt ,
  58 respectively, except that they do not return their result in a static
  59 buffer, but instead use the supplied
  60 .I buf
  61 of size
  62 .IR len .
