           void chomp(char *str) {
                int len;
                if (str == NULL || ((len = strlen(str)) <= 0)) return;
                if (str[len-1] == '\n') str[len-1] = '\0';
           }
           void chop(char *str) {
                int len;
                if (str == NULL || ((len = strlen(str)) <= 0)) return;
                str[len-1] = '\0';
           }
