(seit C++11)
Bietet das Mitglied typedef type, die eine POD-Typ eignet sich für den Einsatz als initialisierten Speicher, richtig für ein Objekt von einer der Typen in Types aufgeführt ausgerichtet ist. Die Größe des Speichers zumindest Len. std::aligned_union bestimmt auch die strengsten (größte) Angleichung Voraussetzung bei allen Types und stellt sie als Konstante alignment_value .
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.
