I have an Ocaml module packed into DLL that is dynamically loaded by
the main C program. What should I do to free all memory taken by Ocaml
runtime when the DLL is unloaded? The following scenario does not
work:
[...]
case DLL_PROCESS_ATTACH:
[...]
caml_startup(argv);
break;
case DLL_PROCESS_DETACH:
value* at_exit = caml_named_value("Pervasives.do_at_exit");
if (at_exit != NULL) caml_callback_exn(*at_exit, Val_unit);
value* compact = caml_named_value("Gc.compact");
if (compact != NULL) caml_callback_exn(*compact, Val_unit);
/* Memory leak! */
Any idea?

This si not possible currently. I agree the OCaml runtime system
should one day provide a cleanup function to do this.

It turned out that at least for Microsoft C runtime things are not
that bad. If you statically link CRT, it will clean up all resources
itself.
