"C-pointers in FFI" question

I can't figure out how to use C-pointers in Stk.
Could anybody help me?

Here is an example:

Let's say there is C function "printhello" in library
"libhello" and it returns pointer wich was declared in
C as:

double* pSignal;

In STk script I write:

(define-external phello()
  :return-type :dynamic-ptr
  :entry-name "printhello"
  :library-name "libhello"

(define p (phello))

Now "p" contains all the data I need, but
how do I access array's elements?

Thanks in advance
