In my library I have this code (yet used in another project) where pwork
is assigned to a shared_ptr:

--------------------------------------------------------------
typedef boost::shared_ptr<boost::asio::io_service::work> io_work_ptr;

// Main io_service
static boost::asio::io_service io_service;
static boost::scoped_ptr<boost::thread> io_service_thread;
static boost::asio::io_service::work* p_work;
static bool thread_started;

bool CreateMainThread()
{
if (!thread_started) {
try {
// create the work object on the heap
p_work = new boost::asio::io_service::work(io_service);

// run the IO service as a separate thread:
io_service_thread.reset (
new boost::thread (
boost::bind (
&boost::asio::io_service::run, &io_service
)
)
);

thread_started = !thread_started;
return true;

} catch (boost::thread_resource_error e) {
// Failed to create the new thread
return false;
}
}
}
--------------------------------------------------------------

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

WaveStream::Test()
{
//Start a new timer or renew it
rx_timer_.expires_from_now( boost::posix_time::milliseconds(500) );

I'm thinking would that be correct if you call timer after async_wait() ?

// We managed to cancel the timer. Start new asynchronous wait.

have You tried restet io_service in this thread, before putting the query on the queue?
io_service.reset()
If thats correct from Your businesses logic.

rx_timer_.async_wait(
boost::bind(&WaveStream::handle_timeout, this, _1)
);
}

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

The timer callback is never called.
Is there a way to know if the io_service is runing?

Daniele.
