Parameters

(none)

Return value

Pointer to the managed object or nullptr if no object is owned.

Example

Run this code 
#include <iomanip>
#include <iostream>
#include <memory>
#include <string>
#include <utility>
class Res
{
    std::string s;
public:
    Res(std::string arg) : s{std::move(arg)}
    {
        std::cout << "Res::Res(" << std::quoted(s) << ");\n";
    }
    ~Res()
    {
        std::cout << "Res::~Res();\n";
    }
private:
    friend std::ostream& operator<<(std::ostream& os, Res const& r)
    {
        return os << "Res { s = " << std::quoted(r.s) << "; }";
    }
};
int main()
{
    std::unique_ptr<Res> up(new Res{"Hello, world!"});
    Res* res = up.get();
    std::cout << *res << '\n';
}

Output: 

Res::Res("Hello, world!");
Res { s = "Hello, world!"; }
Res::~Res();
