  24   24  DESCRIPTION
  25   25         The ffs(), ffsl(), and ffsll() functions finds the first bit set
  26   26         (beginning with the least significant bit) and return the index of that
  27   27         bit.  Bits are numbered starting at one (the least significant bit).
  28   28  
  29   29  
  30   30         The fls(), flsl(), and flsll() functions find the last bit set
  31      -       (beginning with the most significant bit) and return the index of that
       31 +       (beginning with the least significant bit) and return the index of that
  32   32         bit.  Bits are numbered starting at one (the least significant bit).
  33   33  
  34   34  RETURN VALUES
  35   35         The ffs(), ffsl(), and ffsll() functions returns the index of the first
  36   36         bit set.  If i is 0, then they return 0.
  37   37  
  38   38  
  39   39         The fls(), flsl(), and flsll() functions return the index of the last
  40   40         bit set.  If i is 0, then they return 0.
