/** | |
* Implements the IPPROTO_IP/IP_UNICAST_TTL socket option. | |
* | |
* @par Examples | |
* Setting the option: | |
* @code | |
* boost::asio::ip::udp::socket socket(io_service); | |
* ... | |
* boost::asio::ip::unicast::hops option(4); | |
* socket.set_option(option); | |
* @endcode | |
* | |
* @par | |
* Getting the current option value: | |
* @code | |
* boost::asio::ip::udp::socket socket(io_service); | |
* ... | |
* boost::asio::ip::unicast::hops option; | |
* socket.get_option(option); | |
* int ttl = option.value(); | |
* @endcode | |
* | |
* @par Concepts: | |
* GettableSocketOption, SettableSocketOption. | |
