Nicht-Member-Funktionen

swap(std::unique_lock)

 

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

Tauscht die internen Zustände der Lock-Objekte aus.

Parameter

Sonstiges

-

das Lock, mit dem der Zustand getauscht werden soll

Rückgabewert

(keine)

Beispiel

Führen Sie diesen Code aus

#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
