Its simple:

|int main () {||||boost::asio::io_service io_service;||boost::asio::spawn( io_service, [io_service](||boost::asio::yield_context yc)||{ for (;;) { ||boost::asio::deadline_timer timer(io_service); 
timer.expires_from_now(boost::posix_time::seconds(1)); std::cout << "do 
wait" << std::endl; timer.async_wait(yc); std::cout << "woken up" << 
std::endl; |
|} }); io_service.run(); } |
