    pointer release();
    		 (seit C++11)
    See More

    Gibt den Besitz des verwalteten Objekts auf, falls vorhanden. get() liefert nach dem Aufruf nullptr.

    Parameter

    (keine)

    Rückgabewert

    Zeiger auf das verwaltete Objekt oder nullptr, wenn kein Objekt verwaltet wurde, dh der Wert, der durch get() vor dem Aufruf zurückgegeben würde.

    Ausnahmen

    noexcept specification:  
    <tbody> </tbody>
    noexcept
      (seit C++11)

    Beispiel

    #include <memory>
#include <iostream>

struct Foo {
    Foo() { std::cout << "Foo\n"; }
    ~Foo() { std::cout << "~Foo\n"; }
};

int main()
{
    std::cout << "Creating new Foo...\n";
    std::unique_ptr<Foo> up(new Foo());

    std::cout << "About to release Foo...\n";
    Foo* fp = up.release();

    if (up.get() == nullptr)
        std::cout << "Foo is no longer owned by unique_ptr...\n";

    delete fp;
}

    Output: 

    Creating new Foo...
Foo
About to release Foo...
Foo is no longer owned by unique_ptr...
~Foo
