Public predicates

.. index:: call_with_timeout/2 .. _timeout/0::call_with_timeout/2:

call_with_timeout/2 ^^^^^^^^^^^^^^^^^^^^^^^

Calls a goal deterministically with the given time limit (expressed in seconds). Note that the goal may fail or throw an error before exhausting the time limit.

| Compilation flags: | static

| Template: | call_with_timeout(Goal,Timeout) | Meta-predicate template: | call_with_timeout(0,*) | Mode and number of proofs: | call_with_timeout(+callable,+positive_number) - zero_or_one

| Exceptions: | Goal does not complete in the allowed time: | timeout(Goal)

.. index:: call_with_timeout/3 .. _timeout/0::call_with_timeout/3:

call_with_timeout/3 ^^^^^^^^^^^^^^^^^^^^^^^

Calls a goal deterministically with the given time limit (expressed in seconds) returning a reified result: true, fail, timeout, or error(Error).

| Compilation flags: | static

| Template: | call_with_timeout(Goal,Timeout,Result) | Meta-predicate template: | call_with_timeout(0,*,*) | Mode and number of proofs: | call_with_timeout(+callable,+positive_number,--atom) - one
