| | | | | --------------------------------------------------------------------------------------------------------- | | ------------- | | template< std::size_t N, class T > bool is_sufficiently_aligned( T* ptr ); | | (since C++26) |

Checks whether the pointer ptr points to an object whose alignment has a value of at least N.

The behavior is undefined if ptr does not point to an object of type T (ignoring cv-qualification at every level).
