Is this code safe?  hv_iterkey returns a string and a length, but the
string may contain ASCII NUL characters, and hence I cannot use
caml_copy_string directly.

Rich.

CAMLprim value
perl4caml_hv_iterkey (value hev)
{
  CAMLparam1 (hev);
  CAMLlocal1 (strv);
  HE *he = He_val (hev);
  I32 len;
  char *str = hv_iterkey (he, &len);
  strv = caml_alloc_string (len);
  memcpy (String_val (strv), str, len);
  CAMLreturn (strv);
}
