noexcept

  (desde C++11)

Ejemplo

#include <iostream>
#include <thread>
#include <chrono>
 
void foo()
{
    std::this_thread::sleep_for(std::chrono::seconds(1));
}
 
int main()
{
    std::thread t;
    std::cout << "before starting, joinable: " << t.joinable() << '\n';
 
    t = std::thread(foo);
    std::cout << "after starting, joinable: " << t.joinable() << '\n';
 
    t.join();
}

Salida:

before starting, joinable: 0
after starting, joinable: 1
