Re: [Boost-users] [asio] How to know if the io_service is runing

In my library I have this code (yet used in another project) where pwork
is assigned to a shared_ptr:
.....
The timer callback is never called.
I've change the code in this way:
...
--------------------------------------------------------------
typedef boost::shared_ptrboost::asio::io_service::work io_work_ptr;
// Main io_service
static boost::asio::io_service          io_service;
static boost::asio::io_service::work*   p_work;
The io_service::work now is stored into a shared_ptr:

static io_work_ptr p_work;

so I'm pretty sure it is running.
...
bool CreateMainThread()
{
  if (!thread_started) {
    try {
      // create the work object on the heap
      p_work = new boost::asio::io_service::work(io_service);
p_work.reset( new boost::asio::io_service::work(io_service) );

--------------------------------------------------------------
WaveStream::WaveStream() : rx_timer_(io_service)
{
};

WaveStream::Test()
{
  io_service.reset();
  //Start a new timer or renew it
  rx_timer_.expires_from_now( boost::posix_time::milliseconds(500) );
  //Start new asynchronous wait.
  rx_timer_.async_wait(
    boost::bind(&WaveStream::handle_timeout, this, _1)
  );
}

void WaveStream::handle_timeout(const boost::system::error_code& error)
{
 ....
}
--------------------------------------------------------------

I don't know why the handler is not called!
