I have a Connector and … 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 Boost ASIO 13 Years Ago by pseudorandom21 If ASIO had better documentation I could probably have found for myself an answer, but instead... 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. Does it have a tcp socket in there somewhere? Re: Issue with Boost ASIO Acceptor 11 Years Ago by missil9 Hi richieking. I ended up just implementing my own anyway. I have a feeling it had to do with Boost compatability with the machine settings on the one server. My implementation is working as expected now. Thank you for your time. Re: Boost Asio TCP SSL Concurrent Read Write 8 Years Ago by rubberman You need to post your errors and where they are coming from if you want any reasonable help. Asking for people to analyze 250+ lines of code is not usually received well. In any case I don't have time as I am currently out of the country until after the first of the year and have little time for such.

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.

It… 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.

One thing that I see wrong is the declaration of io_service inside of start_accept().
