auto_ptr est un pointeur intelligent qui gère un objet obtenu par l'intermédiaire nouveau et supprime cet objet quand auto_ptr lui-même est détruit. Il peut être utilisé pour fournir une sécurité pour les objets exception allouée dynamiquement, pour le passage de la propriété des objets alloués dynamiquement en fonction, et pour renvoyer les objets à affectation dynamique de fonctions .
Original:
auto_ptr is a smart pointer that manages an object obtained via new and deletes that object when auto_ptr itself is destroyed. It may be used to provide exception safety for dynamically-allocated objects, for passing ownership of dynamically-allocated objects into functions and for returning dynamically-allocated objects from functions.

Copie d'une copie auto_ptr le pointeur et transfère la propriété à la destination: construction exemplaire à la fois et l'affectation copie de auto_ptr modifier leurs arguments de la main droite, et la "copie" n'est pas égal à l'original. En raison de ces sémantique de la copie inhabituelles, auto_ptr ne peuvent pas être placés dans des conteneurs standards. std::unique_ptr est préféré pour ceci et d'autres usages .
Original:
Copying an auto_ptr copies the pointer and transfers ownership to the destination: both copy construction and copy assignment of auto_ptr modify their right hand arguments, and the "copy" is not equal to the original. Because of these unusual copy semantics, auto_ptr may not be placed in standard containers. std::unique_ptr is preferred for this and other uses.
