Socket option for determining whether an IPv6 socket supports IPv6 communication only.
typedef implementation_defined v6_only;
Implements the IPPROTO_IPV6/IPV6_V6ONLY socket option.
Setting the option:
boost::asio::ip::tcp::socket socket(my_context); ... boost::asio::ip::v6_only option(true); socket.set_option(option);
Getting the current option value:
boost::asio::ip::tcp::socket socket(my_context); ... boost::asio::ip::v6_only option; socket.get_option(option); bool v6_only = option.value();
