Registering OCaml values with the C runtime.
This module allows OCaml values to be registered with the C runtime under a symbolic name, so that C code can later call back registered OCaml functions, or raise registered OCaml exceptions.
val register : string -> 'a -> unit
Callback.register n v registers the value v under the name n . C code can later retrieve a handle to v by calling caml_named_value(n) .
val register_exception : string -> exn -> unit
Callback.register_exception n exn registers the exception contained in the exception value exn under the name n . C code can later retrieve a handle to the exception by calling caml_named_value(n) . The exception value thus obtained is suitable for passing as first argument to raise_constant or raise_with_arg .
