aligned_union< Len, Types > Struct Template Reference

Provides the nested type type, which is a trivial standard-layout type of a size and alignment suitable for use as uninitialized storage for an object of any of the types listed in Types. The size of the storage is at least Len. aligned_union also determines the strictest (largest) alignment requirement among all Types and makes it available as the constant alignment_value. If sizeof...(Types) == 0 or if any of the types in Types is not a complete object type, the behavior is undefined. It is implementation-defined whether any extended alignment is supported. The behavior of a program that adds specializations for aligned_union is undefined. More...
