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