Answer 1

One possible approach:(There are many ways to accomplish..also its not good idea to use sleep in your thread)

///Define a mutex
void sleepy()
{
    //try to take mutex lock which this thread will get if main thread leaves that
    //usleep(1.0E15);
}


int main()
{
    //Init the Mutex
    //take mutex lock
    std :: thread sleepy_thread(sleepy);

    //Do your work
    //unlock the mutex...This will enable the sleepy thread to run
    sleepy_thread.join();
}
