| Subject: | FFI: Allocating an array of doubles and initializing it |
Hello,
I'm currently trying to allocate an array of doubles to pass some
values back to Ocaml. However, documentation on this specific topic
seems relatively sparse, and thus I'm not sure if the following is
correct:
CAMLprim value ml_create_float_array (value n, value fill)
{
CAMLparam2(n, fill);
CAMLlocal1(arr);
long i;
long N = Long_val(n);
double D = Double_val(fill);
arr = caml_alloc_shr(N * Double_wosize, Double_array_tag);
for (i = 0; i < N; ++i) {
Store_double_field(arr, i, D);
}
CAMLreturn(arr);
}
Any help appreciated.

PS: I'm using Ocaml 3.09.
