system_error/0 — The Logtalk Handbook v3.47.0 documentation

# `system_error/0`

## 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

## Errors

When called:
