Module Fd_by_descr

module Fd_by_descr: sig .. end

Fd_by_descr is a table of the open Fd.ts, indexed by file descriptor number.

In this interface, we use Raw_fd.t rather than Fd.t to avoid a dependency cycle, because the Fd module can't be defined yet.

type t

include Invariant.S

val create : num_file_descrs:int -> t

val add_exn : t -> Raw_fd.t -> unit

add_exn t fd fails if the file descriptor for fd is already in t.

val find : t -> Import.File_descr.t -> Raw_fd.t option

val remove : t -> Raw_fd.t -> unit

val fold : t -> init:'a -> f:('a -> Raw_fd.t -> 'a) -> 'a

val iter : t -> f:(Raw_fd.t -> unit) -> unit

val sexp_of_t : t -> Sexplib.Sexp.t

add_exn t fd fails if the file descriptor for fd is already in t.
