Completion of error handling

[Markus Elfring]

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

• printf ⇒ hexdump
• signal ⇒ main

[pancake]

sure, will do before 1.2 release

[pancake]

i'm not using signal anymore. sigaction works better. no return value checks yet. will update the code later

[pancake]

checked return values for alarm and sigaction

[pancake]

handling return values for all printf/fprintf calls will mess too much the code and i think the benefits for this are low, so i'm moving this issue to 1.3 for now.

See f8e666d

I suggest to avoid ignorance of return values a bit more.

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?

[pancake]

let's close this for now, we'll see if there's any other missing return value that is not checked properly

[Markus Elfring]

There were update candidates left over.
