I don't think these macros are documented.
You can just use the ___BODY macro. It will give you a ___WORD*
pointer to the body of any subtyped scheme object.
As for having a scheme object body allocated with malloc, I think it
would probably behave badly with the garbage collector.
If you want to allocate a scheme object in c, check the
___alloc_scmobj in lib/mem.c
As an example let's check what the ##make-vector function does in
___SCMOBJ result = ___alloc_scmobj (___sVECTOR, n<<___LWS, ___STILL);
I'm showing you how it allocates the still object as it is the simplest case.
