select.select

rlist: object
    wlist: object
    xlist: object
    timeout as timeout_obj: object = None
    /

Wait until one or more file descriptors are ready for some kind of I/O.

The first three arguments are iterables of file descriptors to be waited for:
rlist -- wait until ready for reading
wlist -- wait until ready for writing
xlist -- wait for an "exceptional condition"
If only one kind of condition is required, pass [] for the other lists.

A file descriptor is either a socket or file object, or a small integer
gotten from a fileno() method call on one of those.

The optional 4th argument specifies a timeout in seconds; it may be
a floating point number to specify fractions of seconds.  If it is absent
or None, the call will never time out.

The return value is a tuple of three lists corresponding to the first three
arguments; each contains the subset of the corresponding file descriptors
that are ready.

*** IMPORTANT NOTICE ***
On Windows, only sockets are supported; on Unix, all file
descriptors can be used.

Kqueue syscall wrapper.

For example, to start watching a socket for input:
>>> kq = kqueue()
>>> sock = socket()
>>> sock.connect((host, port))
>>> kq.control([kevent(sock, KQ_FILTER_WRITE, KQ_EV_ADD)], 0)

To wait one second for it to become writeable:
>>> kq.control(None, 1, 1000)

To stop listening:
>>> kq.control([kevent(sock, KQ_FILTER_WRITE, KQ_EV_DELETE)], 0)
