Elemento definito nell'header <type_traits>
template<std::size_t Len, class... Types> struct aligned_union;		(dal C++11)

Fornisce la type membro typedef, che è un tipo POD adatto per l'uso come deposito non inizializzata, correttamente allineato per un oggetto di uno dei tipi elencati in Types. La dimensione della memoria è almeno Len. std::aligned_union determina anche la (più grande) obbligo di allineamento più stretto tra tutti Types e lo rende disponibile come alignment_value costante.

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.
