It is better to use at least RAII here. This approach is not exception
safe and if io_service.run() throws an exception CoUnintialize() will
not be called.
You're right!
But how can I adapt this code to use RAII?
Maybe is more simple to add a try-catch statement?
Daniele.
Zachary's example does it. You can also use the shared_ptr do it locally in
the function by passing the deleter function.

Or you just write your io_worker_thread() so:

void io_worker_thread()
{
#      if(WIN32)
        struct com_init
        {
             com_init() { CoInitializeEx(...); }
             ~com_init() { CoUninitialize(); }
        } initializer_object;
#      endif

       io_service.run();
}

That's it. ;)
