Completion of error handling

[elfring]

Would you like to add more error handling for return values from functions like the following?

• printf ⇒ parse_options
• signal ⇒ main

I don't understand what you're saying. Could you clarify please?

[elfring]

I suggest to avoid ignorance of return values a bit more.
Would you like to detect every error situation as early as possible?

[cheater]

Sounds good. Seems like you have a good idea of what exactly needs to be done. Want to submit a PR?

[elfring]

Are you interested to apply aspect-oriented software development?
How do you think about to encapsulate error detection and corresponding exception handling as a reusable aspect in your software?

I'm not the developer, I was just interested in your bug report. Here's an idea: implement what you're thinking of (progress isn't huge so you should be able to do this fairly quickly) and show us how it works. What do you think of this?
