I would translate this directly to D:

extern(C) alias Callback = void function(void*);

And don't forget extern(C) on this too:

extern(C) void MyDtaCB(void* pVoid) {

}


And assign it to the struct:

Events.OnData = &MyDtaCB;



Unless you have a link to the wiki that talks about ints, maybe 
that says something different, but I like to keep my C and D code 
that calls it looking pretty much the same when I can.
