Register a 0MQ socket or native fd for I/O monitoring.
register(s,0) is equivalent to unregister(s).
Parameters
----------
socket : zmq.Socket or native socket
A zmq.Socket or any Python object having a ``fileno()``
method that returns a valid file descriptor.
flags : int
The events to watch for. Can be POLLIN, POLLOUT or POLLIN|POLLOUT.
If `flags=0`, socket will be unregistered.

The socket instance to stop polling.

Parameters
----------
timeout : float, int
The timeout in milliseconds. If None, no `timeout` (infinite). This
is in milliseconds to be compatible with ``select.poll()``.
Returns
-------
events : list of tuples
The list of events that are ready to be processed.
This is a list of tuples of the form ``(socket, event)``, where the 0MQ Socket
or integer fd is the first element, and the poll event mask (POLLIN, POLLOUT) is the second.
It is common to call ``events = dict(poller.poll())``,
which turns the list of tuples into a mapping of ``socket : event``.

Return the result of poll as a lists of sockets ready for r/w/exception.
This has the same interface as Python's built-in ``select.select()`` function.
Parameters
----------
timeout : float, int, optional
The timeout in seconds. If None, no timeout (infinite). This is in seconds to be
compatible with ``select.select()``.
rlist : list of sockets/FDs
sockets/FDs to be polled for read events
wlist : list of sockets/FDs
sockets/FDs to be polled for write events
xlist : list of sockets/FDs
sockets/FDs to be polled for error events
Returns
-------
(rlist, wlist, xlist) : tuple of lists of sockets (length 3)
Lists correspond to sockets available for read/write/error events respectively.
