I'm trying to monitor a directory and when a file is added, I will then make  mods to it and move it elsewhere. I'm new to boost, and my understanding is that this is being  executed within a thread, and it acts like its blocking.
 
Any help much appreciated.
 
 
void create_file_handler(const boost::system:error_code &ec,
    const boost::asio::dir_monitor_event &ev) 
{
    cout << "file name: " << ev.filename << endl;
    cout << "    type : " << ev.type << endl;
 
    // now edit file ...
}
 
 
        // from main()
 
        boost::thread t;
 
        {
            boost::asio::io_service io_service; 
            boost::asio::dir_monitor dm(io_service);
 
            dm.add_directory("C:\\Users\\SRD\\DirA");
     
            boost::asio::dir_monitor_event ev = dm.monitor();
            dm.async_monitor(create_file_handler);
             
            t = boost::thread(boost::bind(&boost::asio::io_service::run, boost::refio_service))); 
            boost::system_time time = boost::get_system_time(); 
            time += boost::posix_time::time_duration(0, 0, 1); 
            boost::thread::sleep(time);
        }
 
        t.join();
        io_service.reset();
 
        // now do app stuff ..
