* Implements the IPPROTO_IP/IP_UNICAST_TTL socket option.

*
|
|
* @par Examples
|
|
* Setting the option:
|
|
* @code
|
|
* boost::asio::ip::udp::socket socket(my_context);
|
|
* ...
|
|
* 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(my_context);
|
|
* ...
|
|
* boost::asio::ip::unicast::hops option;
|
|
* socket.get_option(option);
|
|
* int ttl = option.value();
|
|
* @endcode
|

|
|
* GettableSocketOption, SettableSocketOption.
