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.
Note, that the standard doesn't define a named requirement or concept with this name. This is a type category defined by the core language. It is included here as concept only for consistency.
Requirements
Either:
- a scalar type;
- a class type (
class
orstruct
orunion
) that is:
| (until C++11) |
| (since C++11) |
- an array of such type.
