Subject: [Caml-list] GC and interoperability with C
Date: Sun, 08 Jul 2001 21:59:44 -0700	[thread overview]
Message-ID: <3B493A40.1B2985FE@quasar.ipa.nw.ru> (raw)

Hi All,

>From what I see in the documentation, I see no way to 'lock' an OCaml
value on the heap so that it can be safely accessed from C code, and
then 'unlock' it, say, in the finalization function of some
Custom_block. In contrast to Python, e.g., where you just increment and
decrement the reference count.

Is this right?

If this is right, the interaction of OCaml to C becomes one-way, you
cannot safely access OCaml world from arbitrary C code.

Is this right?

Alexander
