I’ve got a service that I need to shut down and update. I’m having difficulties with this in two different cases:

  1. I have some threads that sleep for large amounts of time. Obviously I can’t wait for them to wake up to finish shutting down the service. I had a thought to use an AutoResetEvent that gets set by some controller thread when the sleep interval is up (by just checking every two seconds or something), and triggering it immediately at OnClose time. Is there a better way to facilitate that?

  2. I have one thread that makes a call to a blocking method call (one which I cannot modify). How do you signal such a thread to stop?

    1. I’m not sure if I understood your first question correctly, but have you looked at using WaitForSingleObject as an alternative to Sleep? You can specify a timeout as well as an object to wait on, so if you want it to wake up earlier, just signal the object.

    2. What exactly do you mean by “call to a blocking thread”? Or did you just mean a blocking call? In general, there isn’t a way to interrupt a thread without forcefully terminating it. However, if the call is a system call, there might be ways to return control by making the call fail, eg. cancelling I/O or closing an associated handle.
