val backend : Backend.t
val create : ?num_events:int -> unit -> t

create ?num_events () creates a new instance of a poller. num_events is an optional input that can be used to specify how many events to look for when a poller waits for new events.

val set : t -> Unix.file_descr -> Event.t -> unit

set t fd event updates the state of the set of file descriptors monitored by the poller. Event.none can be used to delete a fd from the set of descriptors that are monitored.

val clear : t -> unit

clear clears the number of i/o events that are ready to be consumed. This should be called after the user consumes all events that are available after wait.

val iter_ready : t -> f:(Unix.file_descr -> Event.t -> unit) -> unit

iter_ready iterates over the events that are ready after a call to wait.

val close : t -> unit
