Returncode handling was reworked throughout the whole driver. Those assignments
were modified according to your suggestion.

Always returns 0;
Correct. They're returning void now.

I asked SO to recount arguments and we've come to a conclusion that
there're in fact 19 args not 18 as the name suggests. 19 args is
I-N-S-A-N-E.
