dns-client 4.4.1 · OCaml Package

type t

The type representing the internal state of the IPv4 stack.

val disconnect : t -> unit Lwt.t

Disconnect from the IPv4 stack. While this might take some time to complete, it can never result in an error.

module UDPV4 : Mirage_protocols.UDPV4

module TCPV4 : Mirage_protocols.TCPV4

module IPV4 : Mirage_protocols.IPV4

val udpv4 : t -> UDPV4.t

udpv4 t obtains a descriptor for use with the UDPV4 module, usually to transmit traffic.

val tcpv4 : t -> TCPV4.t

tcpv4 t obtains a descriptor for use with the TCPV4 module, usually to initiate outgoing connections.

val ipv4 : t -> IPV4.t

ipv4 t obtains a descriptor for use with the IPV4 module, which can handle raw IPv4 frames, or manipulate IP address configuration on the stack interface.

val listen_udpv4 : t -> port:int -> UDPV4.callback -> unit

listen_udpv4 t ~port cb registers the cb callback on the UDPv4 port and immediately return. If port is invalid (not between 0 and 65535 inclusive), it raises Invalid_argument. Multiple bindings to the same port will overwrite previous bindings, so callbacks will not chain if ports clash.

deprecated use UDPV4.listen instead (since mirage-protocols 6.0.0).

val listen_tcpv4 : 
  ?keepalive:Mirage_protocols.Keepalive.t ->
  t ->
  port:int ->
  (TCPV4.flow -> unit Lwt.t) ->
  unit

listen_tcpv4 ~keepalive t ~port cb registers the cb callback on the TCPv4 port and immediately return. If port is invalid (not between 0 and 65535 inclusive), it raises Invalid_argument. Multiple bindings to the same port will overwrite previous bindings, so callbacks will not chain if ports clash. If ~keepalive is provided then these keepalive settings will be applied to the accepted connections before the callback is called.

deprecated use TCPV4.listen instead (since mirage-protocols 6.0.0).

val listen : t -> unit Lwt.t

listen t requests that the stack listen for traffic on the network interface associated with the stack, and demultiplex traffic to the appropriate callbacks.
