std::unique_lock
void swap ( unique_lock & other ) noexcept ;
(seit C++11)

Tauscht die internen Zustände der Sperrobjekte aus.

Inhaltsverzeichnis

Parameter

other - die Sperre, um den Zustand auszutauschen

Rückgabewert

(keine)

Beispiel

Diesen Code ausführen 
#include <iostream>
#include <mutex>
int main()
{
    std::mutex mtx1;
    std::unique_lock<std::mutex> guard1(mtx1);
    std::unique_lock<std::mutex> guard2;
    guard2.swap(guard1);
    if (!guard1 && guard2)
        std::cout << "swapped success\n";
    return 0;
}

Ausgabe: 

swapped success
