std::align_val_t(3) | C++ Standard Libary | std::align_val_t(3) |
NAME¶
std::align_val_t - std::align_val_t
Synopsis¶
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.
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.
