◆ alignof

#define alignof   _Alignof

Return the alignment requirement for type T.

Remarks
If this is not provided a gcc extension is used. If no such extension is provided, a hack through the offsetof macro is used. For the later, T is restricted to simple type names. Arrays or function pointers can only be used through typedef.
