VocabularydebuggerError descriptionThrown by
alien-address and
alien-invoke if an
alien object passed in as a parameter has expired. Alien objects expire if they are saved an image which is subsequently loaded; this prevents a certain class of programming errors, usually attempts to use uninitialized objects, since holding a C address is meaningless between sessions.
NotesYou can check if an alien object has expired by calling
expired?.
