threaded_notify/1

Description

::

threaded_notify(Term) threaded_notify([Term| Terms])

Sends Term as a notification to any thread suspended waiting for it in order to proceed. The call must be made within the same object (:term:this) containing the calls to the :ref:predicates_threaded_wait_1 predicate waiting for the notification. The argument may also be a list of notifications, [Term| Terms]. In this case, all notifications in the list will be sent to any threads suspended waiting for them in order to proceed.

.. note::

This predicate requires a :term:`backend Prolog compiler` providing compatible multi-threading primitives. The value of the read-only :ref:`threads <flag_threads>` flag is set to supported when that is the case.

Modes and number of proofs

::

threaded_notify(@term) - one threaded_notify(@list(term)) - one
