type ipv4addr

The type for IPv4 addresses.

type buffer

The type for memory buffers.

type udpv4

The type for UDPv4 implementations.

type tcpv4

The type for TCPv4 implementations.

type ipv4

The type for IPv4 implementations.

include Mirage_device.S

type +'a io

The type for potentially blocking I/O operation

type t

The type representing the internal state of the device

val disconnect : t -> unit io

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

module UDPV4 : 
  Mirage_protocols.UDP
    with type +'a io = 'a io
     and type ipaddr = ipv4addr
     and type buffer = buffer

    with type +'a io = 'a io
     and type ipaddr = ipv4addr
     and type buffer = buffer
     and type t = tcpv4

val udpv4 : t -> udpv4

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

val tcpv4 : t -> tcpv4

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

val ipv4 : t -> ipv4

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.

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

listen_tcpv4 ~keepalive t ~port cb registers the cb callback on the TCPv4 port and immediatey 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.

val listen : t -> unit io

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