val connect_host : t -> [ `host ] Domain_name.t -> int list -> ((Ipaddr.t * int) * Lwt_unix.file_descr, [ `Msg of string ]) Stdlib.result Lwt.t

connect_host t host ports establishes a connection to host on ports (tried in sequence).

  • raises Failure

    if ports is empty.

val connect_ip : ?shuffle:bool -> t -> Ipaddr.t list -> int list -> ((Ipaddr.t * int) * Lwt_unix.file_descr, [ `Msg of string ]) Stdlib.result Lwt.t

connect_ip ~shuffle t ips ports establishes a connection to ips on ports. If shuffle is provided and true (default: falsE), the list of ips will be mixed before connection attempts.

  • raises Failure

    if ips is the empty list, or ports is the empty list.

val connect : t -> string -> int list -> ((Ipaddr.t * int) * Lwt_unix.file_descr, [ `Msg of string ]) Stdlib.result Lwt.t
