struct IM;
struct C {
IM *impl;
};
int cInit(C* self);
class I {
C handler;
this(){cInit(&handler);}
}
Is there a simple way that I can use handler without the address-of
operator and automatically get *impl?
Something like:
class I {
C handler;
this(){cInit(handler);}
}
And later can use I in a way like this without having to define/write
explicit casts everywhere?
someFunc(C* self);
I myI;
someFunc(myI);
Do you have a clear and correct view of what you want to express, of
the application? How does it look (for us), if you replace IM, C, impl,
cInit, I, handler, with meaningful (and correctly chosen) terms?
Well, ok... even it really doesn't matter a lot.
IM = Implementaiton Context (C-API)
C = Core Context (C-API)
I = Implementation D Class
The C side requires that *impl is the 1st member in the struct/class
whereever it is stored. Hence, the wrapping in a struct and not
directly putting it into a D class.
