Completion of error handling

[elfring]

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

• fputs ⇒ escape
• strdup ⇒ main

[dspinellis]

Sure. If you check for fputs, errors you also need to check errors by printf, etc. Perhaps just check stdout for error before exiting?

I suggest to avoid ignorance of return values a bit more. How do you think about to improve static source code analysis also for your software?

[dspinellis]

Regarding the ignorance of return values, you have to balance the probability of errors against the affect on code readability. That's why I suggest a single check at the end of the program.

Regarding static code analysis, yes it should be a part.

• 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?

Sorry, no.
