Socket option determining whether outgoing multicast packets will be received on the same socket if it is a member of the multicast group.
typedef implementation_defined enable_loopback;
Implements the IPPROTO_IP/IP_MULTICAST_LOOP socket option.
Setting the option:
asio::ip::udp::socket socket(io_service); ... asio::ip::multicast::enable_loopback option(true); socket.set_option(option);
Getting the current option value:
asio::ip::udp::socket socket(io_service); ... asio::ip::multicast::enable_loopback option; socket.get_option(option); bool is_set = option.value();
