Указывает, что тип POD (Plain Old Data) типа. Это означает, что тип совместим с типами используемых в языке программирования C, можно манипулировать с помощью функции C библиотеки: она может быть создана с std::malloc, он может быть скопирован с std::memmove, и т.д., и могут быть обменены с библиотеками C напрямую, ее двоичной форме.

Original:

Specifies that the type is POD (Plain Old Data) type. This means the type is compatible with the types used in the C programming language, can be manipulated using C library functions: it can be created with std::malloc, it can be copied with std::memmove, etc, and can be exchanged with C libraries directly, in its binary form.
