Aligned type. More...
This meta-algorithm solves compiler problem when you need to declare a type
T with alignment equal to another type alignment. For example, the following declaration produces an error in Microsoft Visual Studio 2008 compiler:
In MS VS, the __declspec(align(N)) construction requires that N must be a integer constant (1, 2, 4 and so on) but not an integer constant expression.
The result of this meta-algo is a type
aligned_type<T,Alignment>::type that is
T aligned by
Alignment. For example, with
aligned_type the prevoius example will not generate an error:
and result of this declaration is equivalent to
Alignment template parameter must be a constant expression and its result must be power of two. The maximum of its value is 1024.
