module Lwt_main: sig..end
Main loop and event queue
This module controls the ``main-loop'' of Lwt.
val run : 'a Lwt.t -> 'a
run t calls the Lwt scheduler repeatedly until t terminates,
then returns the value returned by the thread. It t fails with
an exception, this exception is raised.
Note that you should avoid using run inside threads* The calling threads will not resume before run returns.
- Successive invocations of run are serialized: an invocation of run will not terminate before all subsequent invocations are terminated.
val yield : unit -> unit Lwt.t
yield () is a threads which suspends itself and then resumes
as soon as possible and terminates.
Sets of functions executed just before the program exit.
Notes:* each hook is called exactly one time
- exceptions raised by hooks are ignored
val at_exit : (unit -> unit Lwt.t) -> unit
at_exit hook adds hook at the left of exit_hooks
