Description

::

system_error

Throws a system error. Used when runtime execution can no longer proceed. For example, an exception is thrown without an active catcher. This built-in method is declared private and thus cannot be used as a message to an object. Calling this predicate is equivalent to the following sequence of goals:

::

..., context(Context), throw(error(system_error, Context)).

This allows the user to generate errors in the same format used by the runtime.

Modes and number of proofs

::

system_error - error
