-/// Socket option for time-to-live associated with outgoing unicast packets.
-/**
- * Implements the IPPROTO_IP/IP_UNICAST_TTL socket option.
- *
- * @par Examples
- * Setting the option:
- * @code
- * asio::ip::udp::socket socket(io_context);
- * ...
- * asio::ip::unicast::hops option(4);
- * socket.set_option(option);
- * @endcode
- *
- * @par
- * Getting the current option value:
- * @code
- * asio::ip::udp::socket socket(io_context);
- * ...
- * asio::ip::unicast::hops option;
- * socket.get_option(option);
- * int ttl = option.value();
- * @endcode
- *
- * @par Concepts:
- * GettableSocketOption, SettableSocketOption.
