Completion of error handling

[elfring]

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

• malloc ⇒ createLayer
• printf ⇒ printMatrix

[100]

Yeah I think that's definitely something useful, I'm just not sure what the best way to handle this would be. E.g. should it exit upon receiving a null matrix, network, etc. or should we add some other mechanism for checking status built into the library

[elfring]

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

[100]

Yes, it's probably best to detect these within functions as they occur and subsequently exit, but allow functions to return null pointers if they are user-exposed (networks, matrices) and have the user handle those

• 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?
