Definiert in Header <thread>
std::thread::id get_id() noexcept;		(seit C++11)

Gibt die id des aktuellen Threads zurück.

Parameter

(keine)

Rückgabewert

id des aktuellen Threads.

Beispiel

Führen Sie diesen Code aus

#include <chrono>
#include <iostream>
#include <syncstream>
#include <thread>
using namespace std::chrono_literals;
 
void foo()
{
    std::thread::id this_id = std::this_thread::get_id();
 
    std::osyncstream(std::cout) << "thread " << this_id << " sleeping...\n";
 
    std::this_thread::sleep_for(500ms);
}
 
int main()
{
    std::jthread t1{foo};
    std::jthread t2{foo};
}

Mögliche Ausgabe

thread 140113018054400 sleeping...
thread 140113009661696 sleeping...
