type t

An Epoll.Flags.t is an immutable set of flags for which one can register interest in a file descriptor. It is implemented as a bitmask, and so all operations (+, -, etc.) are constant time with no allocation.

sexp_of_t produces a human-readable list of bits, e.g., "(in out)".

include Core_kernel.Flags.S with type t := t
val t_of_sexp : Ppx_sexp_conv_lib.Sexp.t -> t
val sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t
val typerep_of_t : t Typerep_lib.Std.Typerep.t
val typename_of_t : t Typerep_lib.Std.Typename.t

consistent with subset

set union, bitwise or

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

set difference

val intersect : t -> t -> t

bitwise and

val complement : t -> t

bitwise not

val is_empty : t -> Base.Bool.t
val do_intersect : t -> t -> Base.Bool.t
val are_disjoint : t -> t -> Base.Bool.t
val is_subset : t -> of_:t -> Base.Bool.t

is_subset t ~of_ is t = intersect t of_

The names of the flags match the man pages. E.g. in_ = "EPOLLIN", out = "EPOLLOUT", etc.

val none : t

Associated fd is readable

val in_ : t

Associated fd is readable

val out : t

Associated fd is writable

val pri : t

Urgent data available

val err : t

Error condition (always on, no need to set it)

val hup : t

Hang up happened (always on)

val et : t

Edge-Triggered behavior (see man page)

val oneshot : t

One-shot behavior for the associated fd
