Copy a streambuf's contents to a string

Question

Apparently boost::asio::async_read doesn\'t like strings, as the only overload of boost::asio::buffer allows me to create const_buffer

Answer 1

It's really buried in the docs...

Given boost::asio::streambuf b, with size_t buf_size ...

boost::asio::streambuf::const_buffers_type bufs = b.data();
std::string str(boost::asio::buffers_begin(bufs),
                boost::asio::buffers_begin(bufs) + buf_size);
