A18-1-3 - Unofficial Autosar C++ Guidelines Reference

Rule A18-1-3 (required, implementation, automated)

The std::auto_ptr type shall not be used.

Rationale

The std::auto_ptr type has been deprecated since the C++11 Language Standard and is removed from the C++17 Language Standard. Due to the lack of move semantics in pre C++11 standards, it provides unusual copy semantics and cannot be placed in STL containers. The correct alternative is std::unique_ptr, which shall be used instead.

Example

#include <cstdint>
#include <memory>
#include <vector>
void Fn() noexcept
{
std::auto_ptr<std::int32_t> ptr1(new std::int32_t(10)); // Non-compliant
std::unique_ptr<std::int32_t> ptr2 =
std::make_unique<std::int32_t>(10);
// Compliant
std::vector<std::auto_ptr<std::int32_t>> v; // Non-compliant
}
