ip::multicast::outbound

ip::multicast::outbound_interface

Socket option for local interface to use for outgoing multicast packets.

typedef implementation_defined outbound_interface;

Types

Name	Description
container	Determine the container for the specified elements.
rebind	Rebind the traits to a new set of signatures.
receive_cancelled_signature	The signature of a channel cancellation notification.
receive_closed_signature	The signature of a channel closed notification.

Member Functions

Name	Description
invoke_receive_cancelled [static]	Invoke the specified handler with a cancellation notification.
invoke_receive_closed [static]	Invoke the specified handler with a closed notification.

Implements the IPPROTO_IP/IP_MULTICAST_IF socket option.

For IPv4, the outbound interface may be specified using an IPv4 address. For IPv6, an interface index must be used, since an IPv6 address does not uniquely identify a network interface.

Examples

Setting the option:

boost::asio::ip::udp::socket socket(my_context);
...
boost::asio::ip::address_v4 local_interface =
  boost::asio::ip::make_address_v4("1.2.3.4");
boost::asio::ip::multicast::outbound_interface option(local_interface);
socket.set_option(option);
