regarded and expertly designed C++ library projects in the
world.

Inherited from basic_socket.
Close the socket.
boost::system::error_code close( boost::system::error_code & ec);
This function is used to close the socket. Any asynchronous send, receive or connect operations will be cancelled immediately, and will complete with the boost::asio::error::operation_aborted error.
Set to indicate what error occurred, if any.
boost::asio::ip::tcp::socket socket(io_service); ... boost::system::error_code ec; socket.close(ec); if (ec) { // An error occurred. }
For portable behaviour with respect to graceful closure of a connected socket, call shutdown() before closing the socket.
