How to repeat an action with asynchronous timer every x seconds?

[Amiplus]

Hello again,

as the title say, i would like to repeate an action (a system beep, for example) every ten seconds.


Thank you very much

#include <atomic>
#include <chrono>
#include <iostream>
#include <thread>

std::atomic_flag cont = ATOMIC_FLAG_INIT;

struct beep_annoyingly
{
template <typename DURATION>
    void operator()(DURATION duration)
    {
        while(cont.test_and_set()) {
            std::cout << '\a';
            std::this_thread::sleep_for(duration);
        }
    }
};

int main()
{
    using namespace std::literals;
    cont.test_and_set();
    std::thread foo(beep_annoyingly(), 500ms);
    std::cout << "Press enter when you cannot handle this sound anymore";
    std::cin.get();
    cont.clear();
    foo.join();
}

Thank you.

Will this thread be executed asynchronously?

I mean... the while should not block the rest of the program.

Btw, i get:

main.cpp|1885|error: 'literals' is not a namespace-name|
using namespace std::literals;

As you can see output in main is placed after creating new thread with loop inside and it outputs correctly. Also you can hear beep while main function waits for input.
