Summary0004936: "ignore" attribute doesn't work for function's arguments
DescriptionI have an .idl file with the following contents:

=========
void func( [in,ignore] void* param , int x );
=========

After processing this file with "camlidl test.idl" I get following C stub code:

=========
value camlidl_test_func(
    value _v_x)
{
  void *param; /*in*/
  int x; /*in*/
  x = Int_val(_v_x);
  func(param, x);
  return Val_unit;
}
=========

This contradicts the documentation ( http://caml.inria.fr/pub/old_caml_site/camlidl/htmlman/main003.html [^] ), section "3.2 Pointers":
"IDL pointers of kind ignore denote struct fields and function parameters that need not be exposed in the Caml code. Those pointers are simply set to null when converting from Caml to C, and ignored when converting from C to Caml. They cannot occur elsewhere."
Argument "param" was not set to NULL in the C code.
It would be convenient to have an ability to ignore function's arguments setting them to NULL, so, it's more preferrable to fix the code than to fix the documentation.

I'm closing this PR because CamlIDL has been dormant since 2004. It now lives (or at least sleeps) on http://forge.ocamlcore.org/projects/camlidl/ [^] [^] . Anyone who still cares about CamlIDL after all these years is welcome to join the project on forge.ocamlcore.org and breathe some life in it.
