Struct max_align_t vs struct max_align_t

WebIf an object's alignment is made stricter (larger) than max_align_t using _Alignas, it has extended alignment requirement. A struct or union type whose member has extended alignment is an over-aligned type. It is implementation-defined if over-aligned types are supported, and their support may be different in each kind of storage duration . WebSep 14, 2024 · std::max_align_t is a trivial standard-layout type whose alignment requirement is at least as strict (as large) as that of every scalar type. Notes Pointers returned by allocation functions such as std::malloc are suitably aligned for any object, which means they are aligned at least as strictly as std::max_align_t .
