<h4>Description</h4>
|
|
|
|
<pre>threaded(Conjunction)</pre>
|
|
<p>
|
|
Proves each goal in a conjunction of goals in its own thread. The argument can also be a conjunction of messages, either to <em>self</em> or to an explicit object. A call to this predicate blocks until all individual threads terminate. This predicate is transparent to cuts and exceptions.
