typedef asio::ip::detail::socket_option::unicast_hops< IPPROTO_IP, IP_TTL, IPPROTO_IPV6, IPV6_UNICAST_HOPS> asio::ip::unicast::hops

Socket option for time-to-live associated with outgoing unicast packets.

Implements the IPPROTO_IP/IP_UNICAST_TTL socket option.

Examples

Setting the option:

 asio::ip::udp::socket socket(io_service); 
 ...
 asio::ip::unicast::hops option(4);
 socket.set_option(option);

Getting the current option value:

 asio::ip::udp::socket socket(io_service); 
 ...
 asio::ip::unicast::hops option;
 socket.get_option(option);
 int ttl = option.value();

Concepts:

GettableSocketOption, SettableSocketOption.
