How do I play a mono sound of approx 2500 samples over 500ms using ASIO Audio Driver? I'm really stuck on this. I've never used callbacks before, but the ASIO driver does. I need to use ASIO due to latency issues. Re: performance of boost asio and ACE 13 Years Ago by stereomatching looks like I don't have to worry about the problems of performance The other problem is asio steady or not?

Is there a way to determine bytes available to read using the asio::ip::tcp::iostream ? I really like the tcp iostream because it's super-easy to use, but I haven't found it exactly feature-packed.

Going to bed soon... So I will answer only your first question. Your regular expression is incorrect. the {#} is not supposed to be used the way you do. If you want to match 3 of w's, just spell it out... i.e. /^www\.[^\.]*\.[^\.]*\.\w+{2,4}/i That's just an example which is not a perfect solution. It… Re: Boost asio/regex noob needs a helping hand-- 14 Years Ago by Intrade Okay, I have a question. What exactly does the i at the end represent for each of your patterns? Just the literal i, or does it have some other meaning? I don't see it mentioned on Boost regex, nor have I encountered it in Lua. I don't expect you to answer anytime soon... you're asleep ;p Re: Boost asio/regex noob needs a helping hand-- 14 Years Ago by Taywin The 'i' indicates the match to 'ignore case'. You may need to read about regexp somewhere else because it is standard. Sorry, still don't have much time to answer your 2nd question. Hope someone else will handle this. Need to get going and won't be back until late here.

Producer will put data/job into a queue. Consumer will deque the queue and work on that data. Usually you should have one producer thread and multiple consumer threads. In your case one data preparation thread and multiple data processing threads.
