I would like to quote a bit which shows the underlying issues with the
used programming language.
"...
Exceptional events occur. But, since they are exceptional, they occur
very rarely. This is exactly the problem with them. In programming
courses you learn to always handle any possible event. But, in practice,
most programmers just ignore them. If you look at this problem in
detail, you see that these events are not ignored where they actually
occur, but at some higher level.

I do not want to prove this so far because return value ignorance might
be a common and well-known (bad) coding practice.

It would be nice if C++ exceptions could be used here because they can
not be ignored by default. I guess that the tool "AspectC++" will also
work with C constructs. Do you find the tool "AspeCt-oriented C
compiler" more appealing?

I would not say never. - Exceptional situations are usually expected to
appear seldom.

The efforts for complete error code checking can be reduced by a mixture
of function, class and advice libraries.

It takes a bit more time to become comfortable with evolving software
technologies.
