Callback - Registering OCaml values with the C runtime.

       Module Callback
        : sigend

       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.

       valregister : string->'a->unitCallback.registernv registers the value v under the name n . C code can later retrieve a handle to v by
       calling caml_named_value(n) .

       valregister_exception : string->exn->unitCallback.register_exceptionnexn 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 .
