We don't have a lot of "big project" experience with Go yet, but we would use
it for a plain-old desktop application.

Don't get me wrong, D is great, it has a lot of technically cool things on
board.
As said, those technical things won't b
Hi, I'm mostly doing simple C-API wrappers around C++ code to access
thigns from D. However, I wanted to try how far I can come using C++
directly.
I have the following C++ code in namespace N:
class Image : public Object {
Error create(int w, int h, uint32_t p) noexcept;
}
And I have

Yes, great! Thanks. I could extend the code now. But I get a next problem:

If so, try nuking `work` away.

I have the following C++ function signature:
uint _begin(Image& image, const InitParams* initParams)

But this compiles to the following signature which is not found by

If "Image" is a class then all classes are based as pointers to their
respective object.
Hi, ok. Didn't remember that this is always the case.
So passing a ref to a class is kind of redundant.
Yes, that's why I was confused.

You want to use a struct which isn't passed by pointer, but by value.
Which will then give you the signature you want.
In addition to my other post, using struct won't give the correct
signature. That's the signature I need:

That's why there's `extern(C++, class) struct Image`, see

I have an extern(C) function in a DLL with this signature:

I call it like this:

Shouldn't the result be a pointer?
