|Summary||0006434: caml_final_release is not declared in finalise.h|
|Description||Should be clear from subject.|
|Tags||No tags attached.|
This is a primitive that you're supposed to call from OCaml, not from C, so it doesn't need to be declared in the .h. Do you have a use case for calling it from C?
I think I did, but not I'm not sure. A previous design of finalizers in ocaml-zmq was supposed to have a finalizer that doesn't terminate for a long time. But we went away from that design already.
Generally, wouldn't the use cases for calling it from C be the same as for finalizers written in OCaml?
There are two kinds of finalisers/finalizers:
Finalizers are written in C and used for custom objects.
Finalisers are written in OCaml and used with Gc.finalise.
caml_final_release is for the second kind. I suppose you might want to call it from a C primitive called by your OCaml finalisation function, but I don't see much use for that. At worst you can do it with a callback (!) or call it before you call your C primitive.
|Does caml_final_release not work with finalizers written in C? I don't see anything conceptually different between releasing the runtime from a C finalizer or OCaml finalizer.|
|A C finalizer runs in the middle of garbage collection. That's definitely not a safe point for releasing the runtime.|
