Indeed what you get with good use of goto. The rule is basically to
only goto in the forward direction within a function. It's very
simple, and it can make code *tremendously* more readable.
int thing(params) {
if (error)
goto handle_errors;
if (other_error)
goto handle_errors;
if (third_error)
goto handle_errors;
/* all conditions have been checked, it's safe to do the thing */
for (num = 0; num < times; num++)
do_thing();
return 0;
handle_errors:
clean_up();
return 1;
}
