Your const does not make sense. Please read C standard how qualifiers
are applied.

Nothing improved here.

This is a friendly reminder during the review process.

It seems my or other reviewer's previous comments were not fully
addressed. Maybe the feedback got lost between the quotes, maybe you
just forgot to apply it. Please go back to the previous discussion and
either implement all requested changes or keep discussing them.

Thank you.


Best regards,
Krzysztof
