If an Interface is a standard object or structure (and not a class) then how does it fit in with C++ or PortablE for that metter?

FastFileSystem I'm really starting wonder if you are playing a subtle trolling game or if I have to revoke my previous accustation of intelligence.

I hope neither is really true and we a just not explainiing our selves very well!

You can store the interface in your object. This helps encapsulates the os specific parts and you don't to do any variable renaming stunts to call the libraries, I used thi approach extensivly in my blender port.

rough ly speaking, pseudo code.

class System()
{
      struct m_DOSIFace;

}

System::Contructor()
{
    this.m_DOSIFace = OpenInterface("dos.library");
}

System::Print()
{
    this.m_DOSIface->Printf("this is what I'm trying explian");
}

System::Destructor()
{
   CloseInterface(this.m_DOSIFace);
}

sys = new System()

sys.Print();

But because this is a old API, and concept of Objects as we know it today did not exist back in 80's when they designed the AmigaOS API for BCPL and Assembler language.

But wasn't BOOPSI developed in the 90's? In any case they certainly knew about OOP concepts like classes, objects and inheritence if the RKM is anything to go by.

And, Intituion is written in C. And wasn't designed for BCPL which was a DOS thing.

Reread the PDF on migrating to OS4 in the SDK. For what purpose now? I've re-read it heaps of times.

You clearly didn't understand them.

Sorry? How does FastFileSystem relate to an Exec Interface?

I was merely asking about what Deniil715 meant by "real object orientation here, using C++ or PortablE" in relation to an Interface.

So yes I'm not explaining myself that well! Or not asking that well.

THat's interesting. Though I would associate System with Exec myself I can see how it's intended for a generic DOS API.

And I'm developeing a 68k app ported to 0S4 with little issue, it was much harder to get it working on 68k gcc than on os4.

I've heard about 68K GCC being a pain and have some experience trying to use it.

Understand what now? Migrating? Interfaces. I understand them fine. So what's the problem here?

Oh yes, haven't you heard of it? It's the sexy version of the 68K CPU, with sexy sex. The 69K contains the Motorola SEX instruction! LOL! *
