    Perhaps not, however.  strlen() may be nothing more than the
 use of strchr() to search for the zero terminator!  If that is
 the case, then we may simplify our function and use the standard
 strchr() function to find the terminator and then work backward.

static char *notrail(char *string)
{
   char *end;
   if (string && *string)
   {
      for(end = strchr(string, 0) - 1;
         isspace(*end) && (end >= string);
         end--);
      *++end = (char)0;
   }
   return string;
}

 It is rather pretty this way, isn't it?
