type of a registered call back function

val register_default_impl : unit -> unit

Registers the default event loop based on poll(). This must be done before connections are opened.

Once registered call run_default_impl in a loop.

val run_default_impl : unit -> unit

Runs one iteration of the event loop. Applications will generally want to have a thread which invokes this in an infinite loop.

type callback_id

an individual event registration

val register_any : 'a Libvirt.Connect.t ->
       ?dom:'a Libvirt.Domain.t ->
       callback -> callback_id

register_any con ?dom callback registers callback to receive notification of arbitrary domain events. Return a registration id which can be used in deregister_any.

If ?dom is None then register for this kind of event on all domains. If dom is Some d then register for this kind of event only on d.

val deregister_any : 'a Libvirt.Connect.t -> callback_id -> unit

deregister_any con id deregisters the previously registered callback with id id.

type timer_id

an individual timer event

val add_timeout : 'a Libvirt.Connect.t -> int -> (unit -> unit) -> timer_id

add_timeout con ms cb registers cb as a timeout callback which will be called every ms milliseconds

val remove_timeout : 'a Libvirt.Connect.t -> timer_id -> unit

remove_timeout con t deregisters timeout callback t.
