.. abstractmethod:: register(fileobj, events, data=None)
.. abstractmethod:: register(fileobj, events, data=None, *, extra_events=0)

Register a file object for selection, monitoring it for I/O events.

*fileobj* is the file object to monitor. It may either be an integer
file descriptor or an object with a ``fileno()`` method.
*events* is a bitwise mask of events to monitor.
*data* is an opaque object.
*extra_events* is the extra events people want to use. All of the events are defined in :mod:`select` module.

This returns a new :class:`SelectorKey` instance, or raises a
:exc:`ValueError` in case of invalid event mask or file descriptor, or

Change a registered file object's monitored events or attached data.

This is equivalent to :meth:`BaseSelector.unregister(fileobj)` followed
by :meth:`BaseSelector.register(fileobj, events, data)`, except that it
