Hi Ovanes,
Well, my suggestion was the following: If the socket is blocked in a thread, the thread is blocked as well (and luckily boost::thread recognizes it as an iterruption point). Issue interrupt to that thread and the socket's wait will be interrupted. I don't remember If the socket is consistent after this operation, but I know it worked and I was able to close it as if nothing happened.
Hope that clarifies the issue,
Ah, right. Yes it does. That seems rather tricky to implement. I just had a little try on it and I noticed that in order to interrupt the thread calling the blocking wait one would need this thread's boost::thread object. Which cannot be obtained from the this_thread::id. So each thread calling that interruptable receive would have to have it's boost::thread object to pass it to the function, right? I can't see how I could expose all this to the interface of this method. I think it has to be closer to asio. Cheers, Stephan
