Subject: [Boost-users] boost::asio::streambuf question
From: Amit Sonawane (asonawane_at_[hidden])

I am using Asio in Boost version 1.36.0 and I have a question regarding


Code extract:

Class A


boost::asio::streambuf buf;//class member


void Read()


boost::asio::async_read_until(socket, buf,



void DoSomething(const boost::system::error_code& ec, std::size_t
bytes_transferred)//class function


If(!ec && (bytes_transferred != 0))


boost::asio::streambuf::const_buffers_type bufs =;

s(boost::asio::buffers_begin(bufs),boost::asio::buffers_begin(bufs) +

//Do something with the data in s;


//Here I need to call async_read_until again, but buf still has the data
read in the earlier call so, it calls the DoSomething handler again
thus repeating //the process.






My question is how do I clear the contents of buf before calling
async_read_until again. I tried reading into a local variable but
boost::asio::streambuf is noncopyable. Is there a better way to do what
I am trying to do. Any help is greatly appreciated.
