# std::align_val_t

From cppreference.com
< cpp‎ | memory‎ | new

Defined in header `<new>` |  |
enum class align_val_t : std::size_t {}; |  | (since C++17)

Both new-expression and delete-expression, when used with objects whose alignment requirement is greater than `__STDCPP_DEFAULT_NEW_ALIGNMENT__`, pass that alignment requirement as an argument of type `std::align_val_t` to the selected allocation/deallocation function.

### [edit] Notes

Alignment (as obtained by alignof) has the type std::size_t, but placement forms of allocation and deallocation functions that take std::size_t as an additional parameter are already in use, so this type is used instead.
