struct aligned_union;
(desde C++11)
Proporciona la type miembro typedef, que es un tipo POD adecuado para uso como almacenamiento sin inicializar, correctamente alineados para un objeto de cualquiera de los tipos enumerados en Types. El tamaño de almacenamiento es de al menos Len. std::aligned_union determina también la más estricta (el más grande) requisito de alineación entre todos Types y la hace disponible como 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.
