Module Cf_ip4_proto

module Cf_ip4_proto: sig .. end

The AF_INET address family (for use with TCP and UDP over IPv4).

module AF: Cf_socket.AF  with
    type tag_t = [ `AF_INET ] and
    type address_t = Cf_ip4_addr.opaque Cf_ip4_addr.t * int

The address family module for IPv4 transports.

type mreq_t = {

	`imr_multiaddr : Cf_ip4_addr.multicast Cf_ip4_addr.t;`
	`imr_interface : Cf_ip4_addr.unicast Cf_ip4_addr.t;`

}

The multicast request type

The following socket options are available on sockets of AF_INET family.

val ip_ttl : (int, [ `AF_INET ], 'a) Cf_socket.sockopt_t

Set the unicast hop count for the socket.

val ip_add_membership : (mreq_t, [ `AF_INET ], [ `SOCK_DGRAM ]) Cf_socket.sockopt_t

Add the socket to the membership of a multicast group.

val ip_drop_membership : (mreq_t, [ `AF_INET ], [ `SOCK_DGRAM ]) Cf_socket.sockopt_t

Drop the socket from the membership of a multicast group.

val ip_multicast_if : (Cf_ip4_addr.unicast Cf_ip4_addr.t, [ `AF_INET ], [ `SOCK_DGRAM ])
       Cf_socket.sockopt_t

The primary network interface address for sending to multicast destinations.

val ip_multicast_ttl : (int, [ `AF_INET ], [ `SOCK_DGRAM ]) Cf_socket.sockopt_t

The multicast hop count for the socket.

val ip_multicast_loop : (bool, [ `AF_INET ], [ `SOCK_DGRAM ]) Cf_socket.sockopt_t

Enable multicast loopback on the socket.

The following socket options are available on sockets of AF_INET and AF_INET6 address/protocol families.

val siocgifaddr : ([ `AF_INET ], 'a) Cf_socket.t ->
       string -> [> Cf_ip4_addr.unicast ] Cf_ip4_addr.t

Use siocgifaddr sock name with any `AF_INET address family socket sock to get the primary IP address for the name interface.
