Hi,

to play with the c-interface I tried to change the digest module to allow 
calculating a md5 sum piece by piece (i.e. making the function init, 
updtae and finalize avalable).
one question about the parameters of

external md5_new : unit -> md5_context = "md5_new"

should it be:

CAMLprim value md5_new()
{
CAMLparam0();
...
CAMLreturn(...);
}

or
CAMLprim value md5_new(value unit)
{
CAMLparam1(unit);
...
CAMLreturn(...);
}


as it receives a unit-paramter?
(the same for returning unit: CAMLreturn0 or CAMLreturn(Val_unit) ? )

thanks for answering,
  Michael
