376Generate a global/object/player/map-specific event with the given arguments.
377
378This API is preliminary (most likely, the EVENT_KLASS_xxx prefix will be
379removed in future versions), and there is no public API to access override
380results (if you must, access C<@cf::invoke_results> directly).

394Just because you have a perl object does not mean that the corresponding
395C-level object still exists. If you try to access an object that has no
396valid C counterpart anymore you get an exception at runtime. This method
397can be used to test for existence of the C object part without causing an
398exception.
