Is void initialization not good enough?
IIRC it's something like:
ubyte[] buf = void;
That gives me a) no buffer, who's pointer is b) not initialized to null.
I want instead a defined pointer, to a valid array, that is initialized
to zero.
Anyway, I think the flaw in my proposal is the use of a GC. Since we
don't get the memory directly from the operating system, but from a
memory pool in the GC, it is generally 'recycled' and already used
memory. It has to be zeroed out manually, unless there was a way to
tell the OS to rebind some virtual memory addresses in our program to
this magic 'zero page'.
What would be nice is a GC that would just track system-allocated
memory blocks. What would be really great is if you could allocate a
block with malloc/calloc (or something else) and later pass ownership
to the GC, so that the GC calls free (or something else) when all
references disappear. But I'm not sure how you can do that efficiently.
