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}). 13 14@end deftypefn 15 16*/ 17 18 19int 20bcmp (from, to, count) 21 char *from, *to; 22 int count; 23{ 24 int rtnval = 0; 25 26 while (count-- > 0) 27 { 28 if (*from++ != *to++) 29 { 30 rtnval = 1; 31 break; 32 } 33 } 34 return (rtnval); 35} 36 37
