hine><span class=font-tt>dimy</span></span> are dependent
(determined from the dimensions of the big array argument),
hence ignored. The two-dimensional array <span class=machine><span class=font-tt>d</span></span>, although marked <span class=machine><span class=font-tt>[in,out]</span></span>,
is a big array, hence passed as an input that will be modified in
place by the C function <span class=machine><span class=font-tt>p</span></span>. The Caml function has no outputs.
