What is the right way to create a class instance and a return
it as a
pointer? Also in such a way that it is not claimed by GC.
There is
another callback for object deletion.
Why would you want to return an object as a pointer? All
classes are reference types. But if you actually do want to
return an object as a pointer you can just cast it to void*.
I am writing a D binding for the LV2 audio plugin API. The
instantiate function expects a void* return. I wouldn't use void*
casts in D code which doesn't interface with C.
The cast worked, thanks.
