Could publish the prototype and specification  for  the  DLL
function  that  you are trying to write? If were doing it, I
should pass the address of the first array element,  because
it  would be also the start of the raw array data in memory.
Of course, a sufficient number of elemnts would have  to  be
pre-allolcatd  in  the  calling  code, and you can also pass
that, to make sure the DLL does not try to  write  past  the
array boundary.
