One more question about this: can I interface a C function in such a way 
that it uses an OCaml float array to store its output data, i.e. pass 
&(Double_field(ml_output,0)) as a double* "output parameter"?

Of course, I could always go through a bigarray, or use intermediate 
storage. But is there a direct way to do this?
