struct aligned_union;
(depuis C++11)
Fournit la type membre typedef, qui est un type POD peut être utilisé comme stockage non initialisée, alignée correctement pour un objet de l'un des types énumérés dans Types. La taille de la mémoire est au moins Len. std::aligned_union détermine également l'exigence stricte d'alignement (plus) parmi tous Types et le rend disponible le alignment_value constante .
Original:
Provides the member typedef type, which is a POD type suitable for use as uninitialized storage, correctly aligned for an object of any of the types listed in Types. The size of the storage is at least Len. std::aligned_union also determines the strictest (largest) alignment requirement among all Types and makes it available as the constant alignment_value.
