I think we want to get return error ?

The reason why it was using |= is that it should call all function
without break even though it was error
(Maybe first/last error is very OK).

So, we want to is maybe like this (it uses last error)

	int ret = 0;

	for_each() {
		int __ret;

		__ret = xxx();
		if (__ret < 0) {
			...
=>			ret = __ret;
		}
	}

=>	return ret;


Thank you for your help !!
