That worked! :-)

I am currently looking at the asynchromous timer tutorial example. I'm not clear
where the timer thread starts.
Does it start with the call to t.async_wait(print);  in the code below?

#include <iostream>
#include <boost/asio.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/timer.hpp>

void print(const boost::asio::error& /*e*/);

//  some thing to keep the main thread busy
void long_main_process_function();

int main()
{
    boost::asio::demuxer d;
    boost::asio::deadline_timer t(d, boost::posix_time::seconds(5));

    // Is the timer thread starting in this call?
    t.async_wait(print);

    long_main_process_function();

    d.run();

}

void long_main_process_function()
{
     std::cout << "main process long function beginning\n";
    boost::timer t1;
    int temp = 1;
    while(t1.elapsed() < 3){
        if ( t1.elapsed() >= temp){
            std::cout << " tick " << temp << " s\n";
            temp += 1;
        }
    }
    std::cout << "main process long function done\n";
}

void print(const boost::asio::error& /*e*/)
{
  std::cout << "thread finished\n";
}
