Close the socket.
void close();
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.
Thrown on failure. Note that, even if the function indicates an error, the underlying descriptor is closed.
For portable behaviour with respect to graceful closure of a connected
socket, call shutdown()
before closing the socket.
