Standard Library
Below is the API for the OCaml standard library. It's directly copied over from the OCaml Manual, formatted to the Reason syntax and styled accordingly. The API docs are work-in-progress; we'll be polishing these gradually!
If you're targeting JavaScript, the API docs for BuckleScript includes all of below, plus JS-specific APIs.
Module Callback
module Callback: sig .. end
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.
