std::experimental::memory_alignment - cppreference.com (original) (raw)

| | | | | ---------------------------------------------------------------------------------- | | ------------------- | | template< class T, class U = typename T::value_type > struct memory_alignment; | | (parallelism TS v2) |

If is_simd_mask_v<T> is true and U is bool, or if is_simd_v<T> is true and U is a vectorizable type, provides the member constant value equal to the minimum alignment of a pointer passed to a load constructor, copy_from function, or copy_to function. For any other types T and U, there is no member value.

If the program adds specializations for std::memory_alignment or std::memory_alignment_v(since C++17), the behavior is undefined.
