Can I suggest that you modify the check_null_empty_* to pass
in an errno that should be used in the case of an empty string?

You are special casing checks to force an EINVAL.

Hmm.  I wonder if EINVAL is always appropriate for an empty string.
It could just be wrong in check_null_empty_str.

Thanks for doing this due diligence.
