Re^2: Perl function calls.

This method actually did not produce any failure. Yes that correct,die is preferred way. I have used auto die in the script. But I'd like to know/learn how it works with the return message.

It would be really helpful for me if you can help me understand it.

Well, if it didn't return failure, then I'm not sure how you can say your error code didn't work. If there's no failure for it to catch, then of course it won't run. As it is, your error code should work fine if the function is expected to return an error string on failure. Since the function doesn't return an error string in any branch, the error will never be picked up.
