Defined in header <cstddef>
typedef /*implementation-defined*/ max_align_t;
(seit C++11)
std::max_align_t ist ein POD-Typ, deren Ausrichtung Voraussetzung ist mindestens so streng sind (so groß) wie jeder skalaren Typ .
Original:
std::max_align_t is a POD type whose alignment requirement is at least as strict (as large) as that of every scalar type.

[Bearbeiten] Notes

Pointers wieder durch Zuweisung Funktionen wie std::malloc in geeigneter Weise für jedes Objekt ausgerichtet, was bedeutet, dass sie mindestens so streng wie std::max_align_t ausgerichtet sind .
Original:
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 ist in der Regel gleichbedeutend mit dem größten skalaren Typs, die long double ist auf den meisten Plattformen und seine Ausrichtung Voraussetzung ist entweder 8 oder 16 .
Original:
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.

int main()
{
    std::cout << alignof(std::max_align_t) << '\n';
