Inherited from socket_base.
Socket option to specify whether the socket lingers on close if unsent data is present.
typedef implementation_defined linger;
Implements the SOL_SOCKET/SO_LINGER socket option.
Setting the option:
boost::asio::ip::tcp::socket socket(io_context); ... boost::asio::socket_base::linger option(true, 30); socket.set_option(option);
Getting the current option value:
boost::asio::ip::tcp::socket socket(io_context); ... boost::asio::socket_base::linger option; socket.get_option(option); bool is_set = option.enabled(); unsigned short timeout = option.timeout();
