A selector supports registering file objects to be monitored for specific I/O events. A file object is a file descriptor or any object with a `fileno()` method. An arbitrary object can be attached to the file object, which can be used for example to store context information, a callback, etc. A selector can use various implementations (select(), poll(), epoll()...) depending on the platform. The default `Selector` class uses the most efficient implementation on the current platform. Nct)a3Register a file object. Parameters: fileobj -- file object or file descriptor events -- events to monitor (bitwise mask of EVENT_READ|EVENT_WRITE) data -- attached data Returns: SelectorKey instance Raises: ValueError if events is invalid KeyError if fileobj is already registered OSError if fileobj is closed or otherwise is unacceptable to the underlying system call (if a system call is made) Note: OSError may or may not be raised NotImplementedErrorrrrrs rregisterzBaseSelector.register_s *"!r ct)ajUnregister a file object. Parameters: fileobj -- file object or file descriptor Returns: SelectorKey instance Raises: KeyError if fileobj is not registered Note: If fileobj is registered but has since been closed this does *not* raise OSError (even if the wrapped syscall does) r7)rrs r unregisterzBaseSelector.unregisterv ""!r cZ||||||S)ayChange a registered file object monitored events or attached data.

This is used by unregister() so we can unregister an object that was previously registered even if it is closed.
