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__.Import.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__.Import.Time_ns.Span.t ‑> unit
val set_repeating : ?⁠after:Core__.Import.Time_ns.Span.t ‑> t ‑> Core__.Import.Time_ns.Span.t ‑> unit
val clear : t ‑> unit

clear t causes t to not fire anymore.

type repeat = {
fire_after : Core__.Import.Time_ns.Span.t;
interval : Core__.Import.Time_ns.Span.t;
}
val get : t ‑> [ `Not_armed | `Fire_after of Core__.Import.Time_ns.Span.t | `Repeat of repeat ]

get t returns the current state of the timer t.
