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::align – std::align Synopsis Defined in header<memory> void *align(std::size_t alignment, std::size_t size, (since C++ 11) void *&ptr, std::size_t &space); Given a pointer ptr to a buffer of size space, returns a pointer aligned by the specified alignment for size number of bytes and decreases space argument by the number of bytes used for alignment. The…
