Module `Linux_ext.Timerfd`

module Clock : sig ... end

Clock used to mark the progress of a timer.

module Flags : sig ... end

type t = private Core.Unix.File_descr.t

val compare : t -> t -> int

val sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t

val to_file_descr : t -> Core.Unix.File_descr.t

val create : (?flags:Flags.t -> Clock.t -> t) Core.Or_error.t

create ?flags clock creates a new timer file descriptor. With Linux 2.6.26 or earlier, flags must be empty.

val set_at : t -> Core.Time_ns.t -> unit

set_at t at and set_after t span set t to fire once, at at or after span. set_after treats span <= 0 as span = 1ns; unlike the underlying system call, timerfd_settime, it does not clear the timer if span = 0. To clear a timerfd, use Timerfd.clear.

set_repeating ?after t interval sets t to fire every interval starting after after (default is interval), raising if interval <= 0.

val set_after : t -> Core.Time_ns.Span.t -> unit

val set_repeating : 
  ?after:Core.Time_ns.Span.t ->
  t ->
  Core.Time_ns.Span.t ->
  unit

val clear : t -> unit

clear t causes t to not fire anymore.

type repeat = {

fire_after : Core.Time_ns.Span.t;
interval : Core.Time_ns.Span.t;

}

val get : 
  t ->
  [ `Not_armed | `Fire_after of Core.Time_ns.Span.t | `Repeat of repeat ]

get t returns the current state of the timer t.
