Calling (
has the effect that when the specified object is being garbage-collected,
EXT:FINALIZE object function)( will be executed.FUNCALL function object)
Calling (
has a similar effect, but only as long as the
EXT:FINALIZE object function
guardian)guardian has not been garbage-collected:
when object is being garbage-collected, ( will be executed.
If the FUNCALL function
object guardian)guardian is garbage-collected before object
is, nothing happens.
The time when “the object is being garbage-collected” is
not defined deterministically. (Actually, it might possibly never
occur.) It denotes a moment at which no references to object
exist from other Lisp objects. When the function is called,
object (and possibly guardian) enter
the “arena of live Lisp objects” again.
No finalization request will be executed more than once.
