Typedef Documentation

typedef boost::asio::detail::socket_option::boolean< boost::asio::detail::custom_socket_option_level, boost::asio::detail::always_fail_option> boost::asio::ip::v6_only

Socket option for determining whether an IPv6 socket supports IPv6 communication only.

Implements the IPPROTO_IPV6/IP_V6ONLY socket option.

Examples

Setting the option:

boost::asio::ip::tcp::socket socket(io_service); 
...
boost::asio::ip::v6_only option(true);
socket.set_option(option);

Getting the current option value:

boost::asio::ip::tcp::socket socket(io_service); 
...
boost::asio::ip::v6_only option;
socket.get_option(option);
bool v6_only = option.value();

Concepts:

GettableSocketOption, SettableSocketOption.
