Thanks for the reply. However, I've confirmed that the boost::asio::deadline_timer object still exists.
The timer object exists, but what about the objects which are accessed from the handler? Can you post some code snippet?
In examples I've found for repeating timers, that the timer is re-scheduled within the handler itself. In my case, the timer is re-scheduled sometime after the handler has run. I wonder if a timer cannot be re-used this way?
The timer can be used in any way, until you don't try to access it simultaneously from multiple threads.
One additional bit of information is that the timer is scheduled for the very first time by the main process, before the worker thread enters io_service::run(). Is there any problem with scheduling a timer with one thread and then re-scheduling it with another?
If you mean something like this: int main() { io_service io; deadline_timer timer(io); timer.expires(...); timer.async_wait(...); thread t(&io_service::run, &io); t.join(); }; then it's ok, because there's no race conditions here: when you access the timer from the main thread, the timer is not running.
