 @deftypefn Supplemental int bcmp (char *@var{x}, char *@var{y}, int @var{count})
 
 Compares the first @var{count} bytes of two areas of memory.  Returns
-zero if they are the same, non-zero otherwise.  Returns zero if
-@var{count} is zero.  A non-zero result only indicates a difference,
+zero if they are the same, nonzero otherwise.  Returns zero if
+@var{count} is zero.  A nonzero result only indicates a difference,
 it does not indicate any sorting order (say, by having a positive
 result mean @var{x} sorts before @var{y}).
