Re: [Boost-users] ASIO async I/O with iostream?

I'd like to be able to skip the buffer and just read directly to the stream with an event to notify me of the arrival of data.

You can use asio::streambuf. It inherits std::streambuf, and you can use it with istream and ostream, just as you do with standard streambufs. But note that any buffer must outlive the async.operation.
