Socket option for time-to-live associated with outgoing multicast packets.
typedef implementation_defined hops;
Implements the IPPROTO_IP/IP_MULTICAST_TTL socket option.
Setting the option:
asio::ip::udp::socket socket(my_context); ... asio::ip::multicast::hops option(4); socket.set_option(option);
Getting the current option value:
asio::ip::udp::socket socket(my_context); ... asio::ip::multicast::hops option; socket.get_option(option); int ttl = option.value();
