Socket option to send keep-alives.
typedef implementation_defined keep_alive;
Implements the SOL_SOCKET/SO_KEEPALIVE socket option.
Setting the option:
boost::asio::ip::tcp::socket socket(io_context); ... boost::asio::socket_base::keep_alive option(true); socket.set_option(option);
Getting the current option value:
boost::asio::ip::tcp::socket socket(io_context); ... boost::asio::socket_base::keep_alive option; socket.get_option(option); bool is_set = option.value();
