Module Linux_ext.Timerfd

module Timerfd: sig .. end

Clock used to mark the progress of a timer.

module Flags: sig .. end

type t = private Core_unix.File_descr.t

val to_file_descr : t -> Core_unix.File_descr.t

val create : (?flags:Flags.t ->
        Clock.t -> t)
       Core_kernel.Std.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_kernel.Std.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_kernel.Std.Time_ns.Span.t -> unit

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

val clear : t -> unit

clear t causes t to not fire any more.

type repeat = {

	`fire_after : Core_kernel.Std.Time_ns.Span.t;`
	`interval : Core_kernel.Std.Time_ns.Span.t;`

}

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

get t returns the current state of the timer t.
