AFAIK, the first design for implementation of vtables was by Bjarne Stroustrup in his paper Multiple Inheritance for C++ in 1986/1987. Pdf at https://www.google.com/goto?url=CAESawHuR6pN4SDa5tLkqrSuoaot... and reissu

One more addition. There is often a distinction made between "language ABI" and "library ABI" in documentation which is highly confusing. The answer is: library API + compiler ABI = library ABI GNU libstdc++ ABI Polic

And yet you make such statements ;-) I often see on HN these sorts of comments whenever C++ is brought up and it really needs to stop. It is wrong, adds no value to the discussion and does a grave injustice to the programming community. We

What are you talking about? None of it is relevant to the point i am making. Also you do not need COM to program in C/C++ directly on Windows API since they are all C interfaces anyway. COM is just an architecture you choose to use or

Oh come on; that is BS and you know it. It is complex/complicated/baroque but for the power, flexibility, real-world-usage that it provides it is worth the effort. The mistake that people make is to try and learn it all at the sam

Asking questions is always a good thing so don't worry about it. It makes us think and check our own understanding too, so we also learn something :-) A nice succinct post by Pavel Khaipov; Copy-on-Write in Modern C++: Why the Standar

Well said. COM was one of the best realizations of "Component-based Software Engineering" and Brad Cox's "Software-IC" model. It was a binary standard and so components could be written in any language and yet be as

COM designers were inspired by C++ but their goals were different. They were designing a language-neutral binary standard (aka ABI) and hence took C++'s approach and tweaked it for their specification. Here is an earlier comment of min
