Parameter TCPV4V6.Stack

type t

The type representing the internal state of the dual IPv4 and IPv6 stack.

val disconnect : t -> unit Lwt.t

Disconnect from the dual IPv4 and IPv6 stack. While this might take some time to complete, it can never result in an error.

module UDP : Tcpip.Udp.S with type ipaddr = Ipaddr.t
module TCP : Tcpip.Tcp.S with type ipaddr = Ipaddr.t
module IP : Tcpip.Ip.S with type ipaddr = Ipaddr.t
val udp : t -> UDP.t

udp t obtains a descriptor for use with the UDP module, usually to transmit traffic.

val tcp : t -> TCP.t

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

val ip : t -> IP.t

ip t obtains a descriptor for use with the IP module, which can handle raw IPv4 and IPv6 frames, or manipulate IP address configuration on the stack interface.

val listen_udp : t -> port:int -> UDP.callback -> unit

listen_udp t ~port cb registers the cb callback on the UDP 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 UDP.listen instead (since mirage-protocols 6.0.0).
val listen_tcp : ?keepalive:Tcpip.Tcp.Keepalive.t -> t -> port:int -> (TCP.flow -> unit Lwt.t) -> unit

listen_tcp ~keepalive t ~port cb registers the cb callback on the TCP 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 TCP.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.
