std::max_align_t is a POD 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 strict as std::max_align_t.
std::max_align_t is usually synonymous with the largest scalar type, which is long double on most platforms, and its alignment requirement is either 8 or 16.
Example
1 2 3 4 5 6 | #include <iostream>#include <cstddef>int main(){ std::cout << alignof(std::max_align_t) << '\n';} |
Possible output:
1 |
