If ever in need to translate C/C++ headers or code to Delphi, this refernece by Rudy Velthuis – a dentist with a strong interest in programming – is the best I could find: Rudy’s Delphi Corner – Pitfalls of converting.
It is written in a pretty version agnostic way, and covers the vast majority of conversion topics.
And it has been updated over time numerous times.
