threaded_exit(Goal) threaded_exit(Goal, Tag)
Retrieves the result of proving
Goal in a new thread. This predicate
blocks execution until the reply is sent to the
this message queue by the thread
executing the goal. When there is no thread proving the goal, the
predicate generates an exception. This predicate is non-deterministic,
providing access to any alternative solutions of its argument.
The argument of this predicate should be a variant of the argument of
the corresponding threaded_call/1-2 call.
When the predicate argument is subsumed by the
threaded_exit/1 call will succeed iff its argument is
a solution of the (more general) goal.
threaded_exit/2 accepts a threaded call identifier tag
generated by the calls to the threaded_call/1-2 and
threaded_once/1-2 predicates. Tags shall
be regarded as an opaque term; users shall not rely on its type.
