type t

a set of events

val empty : t

empty set

The values below define singleton sets containing exactly one event like inp (input) or hup. See epoll_ctl(2) for the events available. Sets can be combined using (land) (intersection) and (lor) (join) and compared using (=).

val inp : t

called "in" in Linux; "in" is an OCaml keyword

val pri : t

val out : t

val rdnorm : t

val rdband : t

val wrnorm : t

val wrband : t

val msg : t

val err : t

val hup : t

val rdhup : t

val wakeup : t

val oneshot : t

val et : t

val (lor) : t -> t -> t

join sets

val (land) : t -> t -> t

intersect sets

val lnot : t -> t

set complement

val test : t -> t -> bool

test x y returns true, if and only if the intersection of the two sets is not empty. The common case is test set x where set is unknown and x is a singleton to check that x is contained in set.

val to_string : t -> string

to_string t return a string representation of t for debugging
