C++ Niszczenie obiektów

-
delete pFoo
/// konieczenie pFoo musi być wskaźnikiem.
// dokonuje się wszystkie czynności potrzebne do zniszczenie obiektu reprezentowanego
// przez wskaźnik:
// *wywołanie destruktora
// *zwalnianie pamięci zajętą przez obiekt, który kończy wtedy definitywnie swoje istnienie




Co się dzieje wtedy z wskaźnikiem do tego obiektu?
Nadal wskazuje on na miejsce w pamięci, w którym jeszcze niedawno egzystował obiekt. Wszelkie próby - odwołanie się do tego obszaru skończą się więc błędem, zwanym naruszeniem zasady dostępu (ang. access violation , awaryjne zniszczenie programu)

 0. Overivew - Packet manager 1. Helm Provenance and Integrity - https://github.com/technosophos/k8s-helm/blob/master/docs/provenance.md - Helm has provenance tools which help chart users verify the integrity and origin of a package. Using industry-standard tools based on PKI, GnuPG, and well-respected package managers, Helm can generate and verify signature files. a) Overview   -  I ntegrity is established by comparing a chart to a provenance record. Provenance records are stored in   provenance files , which are stored alongside a packaged chart. For example, if a chart is named   myapp-1.2.3.tgz , its provenance file will be   myapp-1.2.3.tgz.prov .  -  Provenance files are generated at packaging time ( helm package --sign ... ), and can be checked by multiple commands, notable   helm install --verify . b) The workflow This section describes a potential workflow for using provenance data effectively. Prerequisites: A valid PGP keyp...
