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. Note that, even if the function indicates an error, the underlying descriptor is closed.
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.
