6@deftypefn Supplemental int bcmp (char *@var{x}, char *@var{y}, int @var{count})
7
8Compares the first @var{count} bytes of two areas of memory.  Returns
9zero if they are the same, nonzero otherwise.  Returns zero if
10@var{count} is zero.  A nonzero result only indicates a difference,
11it does not indicate any sorting order (say, by having a positive
12result mean @var{x} sorts before @var{y}).
