*Async I/O Framework*

Type: ``bool``

Help
====

.. code-block:: none

    Asynchronous notification framework. Enable the k_poll() and
    k_poll_signal_raise() APIs.  The former can wait on multiple events
    concurrently, which can be either directly triggered or triggered by
    the availability of some kernel objects (semaphores and FIFOs).

Defaults
========

No defaults. Implicitly defaults to ``n``.
