(** libguestfs bindings for OCaml.

    For API documentation, the canonical reference is the
    {{:http://libguestfs.org/guestfs.3.html}guestfs(3)} man page.
    The OCaml API uses almost exactly the same calls.

    For examples written in OCaml see the
    {{:http://libguestfs.org/guestfs-ocaml.3.html}guestfs-ocaml(3)} man page.
    *)

(** {2 Module style API}

    This is the module-style API.  There is also an object-oriented API
    (see the end of this file and {!guestfs})
    which is functionally completely equivalent, but is more compact. *)

(** {3 Handles} *)

type t
(** A [guestfs_h] handle. *)

exception Error of string
(** This exception is raised when there is an error. *)

exception Handle_closed of string
(** This exception is raised if you use a {!t} handle
    after calling {!close} on it.  The string is the name of
    the function that was called incorrectly. *)

val create : ?environment:bool -> ?close_on_exit:bool -> unit -> t
(** Create a {!t} handle.

    [?environment] defaults to [true].  If set to false, it sets
    the [GUESTFS_CREATE_NO_ENVIRONMENT] flag.

    [?close_on_exit] defaults to [true].  If set to false, it sets
    the [GUESTFS_CREATE_NO_CLOSE_ON_EXIT] flag. *)

val close : t -> unit
(** Close the {!t} handle and free up all resources used
    by it immediately.

    Handles are closed by the garbage collector when they become
    unreferenced, but callers can call this in order to provide
    predictable cleanup. *)

(** {3 Events} *)

type event =
  | EVENT_CLOSE
  | EVENT_SUBPROCESS_QUIT
  | EVENT_LAUNCH_DONE
  | EVENT_PROGRESS
  | EVENT_APPLIANCE
  | EVENT_LIBRARY
  | EVENT_TRACE
  | EVENT_ENTER
  | EVENT_LIBVIRT_AUTH
  | EVENT_WARNING

val event_all : event list
(** A list containing all event types. *)

type event_handle
(** The opaque event handle which can be used to delete event callbacks. *)

type event_callback = event -> event_handle -> string -> int64 array -> unit
(** The event callback. *)

val set_event_callback : t -> event_callback -> event list -> event_handle
(** [set_event_callback g f es] sets [f] as the event callback function
    for all events in the set [es].

    Note that if the closure captures a reference to the handle,
    this reference will prevent the handle from being
    automatically closed by the garbage collector. *)

val delete_event_callback : t -> event_handle -> unit
(** [delete_event_callback g eh] removes a previously registered
    event callback.  See {!set_event_callback}. *)

val event_to_string : event list -> string
(** [event_to_string events] returns the event(s) as a printable string
    for debugging etc. *)

(** {3 Errors} *)

val last_errno : t -> int
(** [last_errno g] returns the last errno that happened on the handle [g]
    (or [0] if there was no errno).  Note that the returned integer is the
    raw errno number, and it is {i not} related to the {!Unix.error} type.

    Some raw errno numbers are exposed by the {!Guestfs.Errno} submodule,
    and we can add more as required.

    [last_errno] can be overwritten by subsequent operations on a handle,
    so if you want to capture the errno correctly, you must call this
    in the {!Error} exception handler, before any other operation on [g]. *)

(** The [Guestfs.Errno] submodule exposes some raw errno numbers,
    which you can use to test the return value of {!Guestfs.last_errno}. *)

module Errno : sig
  val errno_EINVAL : int
  (** Integer value of errno [EINVAL].  See {!Guestfs.last_errno}. *)
  val errno_ENOTSUP : int
  (** Integer value of errno [ENOTSUP].  See {!Guestfs.last_errno}. *)
  val errno_EPERM : int
  (** Integer value of errno [EPERM].  See {!Guestfs.last_errno}. *)
  val errno_ESRCH : int
  (** Integer value of errno [ESRCH].  See {!Guestfs.last_errno}. *)
  val errno_ENOENT : int
  (** Integer value of errno [ENOENT].  See {!Guestfs.last_errno}. *)
  val errno_EROFS : int
  (** Integer value of errno [EROFS].  See {!Guestfs.last_errno}. *)
  val errno_ENOSPC : int
  (** Integer value of errno [ENOSPC].  See {!Guestfs.last_errno}. *)

(** {2 Object-oriented API}

    This is an alternate way of calling the API using an object-oriented
    style, so you can use
    [g#]{{!guestfs.add_drive_opts}add_drive_opts} [filename]
    instead of [Guestfs.add_drive_opts g filename].
    Apart from the different style, it offers exactly the same functionality.

    Calling [new guestfs ()] creates both the object and the handle.
    The object and handle are closed either implicitly when the
    object is garbage collected, or explicitly by calling the
    [g#]{{!guestfs.close}close} [()] method.

    You can get the {!t} handle by calling
    [g#]{{!guestfs.ocaml_handle}ocaml_handle}.

    Note that methods that take no required parameters
    (except the implicit handle) get an extra unit [()] parameter.
    This is so you can create a closure from the method easily.
    For example [g#]{{!guestfs.get_verbose}get_verbose} [()]
    calls the method, whereas [g#get_verbose] is a function. *)
