<h4>Description</h4>
|
||
|
|
|
||
|
|
<pre>threaded_exit(Goal, Options)</pre>
|
||
|
|
<p>
|
||
|
|
Retrieve the result of proving <code>Goal</code> in a new thread. By default, this call blocks execution until the reply is sent to the <em>this</em> thread by the thread executing the goal. This predicate is non-deterministic, providing access to the alternative solutions of its first argument. The option <code>peek</code> may be used to check if the reply is already available on the <em>this</em> thread. The option <code>discard</code> may be used to discard all matching replies.
