well thank you kindly.
what i don't understand yet, is there a way to have the GC in my program only once instead of several times with the dll's.

gc_setProxy is the way, read that article's section again.

Why do you need to do this? It might be more effective to allow multiple GC's.

but surely you can set the GC of the dll to use that of the another. You will need to expose a method to set the GC from the dll..

void SetGC(GC gc);

type of thing...

Where GC is info regarding the GC to do so which I don't know much about. The latest dmd supports hooking ones own GC so it might be just a matter of using those functions to point to the correct gc.
