Completion of error handling

[elfring]

I have looked at a few source files for your current software. I have noticed that some checks for return codes are missing.

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

• mkdir ⇒ prep
• printf ⇒ dump_begin

Checking for errors in mkdir() would totally make sense and I ought to do it. I can't imagine what useful error checking could be done for printf() there, though.

Would you like to detect every error situation as early as possible?

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?

No, not really.
