I believe that only certain boost thread methods such as sleep can be interrupted. What you could do is a loop that calls select with a timeout and only call a blocking accept when there is socket activity or you could loop with a non-blocking accept.

I assume that asio does this much better than what I have described.

Subject: [Boost-users] Interrupting Threads with boost::thread::interrupt()

Hi folks,

I am having issues with boost::thread::interrupt(). As far as I understood, calling this function will throw an exception in the corresponding thread. How can deal with blocking functions, such as a calls to accept() or when a thread is waiting on a condition variable to change? Basically the thread blocks somewhere in a while (true) loop.

Injecting interruption points manually with
boost::this_thread::interruption_point() does not seem to help here either. boost::thread::interrupt() (or interrupt_all in a thread_group), simply does not return.

Regards,

   Matthias
