How to asynchronously read to std::string using Boost::asio?

Question

I\'m learning Boost::asio and all that async stuff. How can I asynchronously read to variable user_ of type std::string? Boost::asio::buffer(user_)

Answer 1

This isn't intended to be an answer per se, but just a lengthy comment: a very simple way to convert from an ASIO buffer to a string is to stream from it:

asio::streambuf buff;
asio::read_until(source, buff, '\r');  // for example

istream is(&buff);
is >> targetstring;

This is a data copy, of course, but that's what you need to do if you want it in a string.
