412Generate a global/object/player/map-specific event with the given arguments.
413
414This API is preliminary (most likely, the EVENT_KLASS_xxx prefix will be
415removed in future versions), and there is no public API to access override
416results (if you must, access C<@cf::invoke_results> directly).

430Just because you have a perl object does not mean that the corresponding
431C-level object still exists. If you try to access an object that has no
432valid C counterpart anymore you get an exception at runtime. This method
433can be used to test for existence of the C object part without causing an
434exception.
