C++ concepts: PODType

< cpp‎ | concept

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.

This type requirement is deprecated in the C++ standard. All of its uses have been replaced by the more refined type requirements, such as TrivialType

(since C++20)

[edit] Requirements


  • a scalar type;
  • a class type (class or struct or union) that:
  • is an aggregate type;
  • has no non-static members that are non-POD;
  • has no members of reference type;
  • has no user-defined copy constructor;
  • has no user-defined destructor;
(until C++11)
(since C++11)
  • an array of such type.
