[Boost-users] [asio] serial_port::async_read_some() and scalable buffers

Hello, I have a std::vector of bytes that I am passing into boost::asio::buffer(). The vector originally is of size 0. Basically, I want the vector to be resized by asio depending on how much data is read in. I don't want to choose an arbitrary upper-limit for the buffer. Is this possible? Below is an example of what I am doing: std::vectorboost::uint8_t stream; m_port.async_read_some( boost::asio::buffer( stream ), boost::bind( &SerialClient::ReadCompleted, this, stream, error, bytes_transferred ) ); However, the above code will never read any data because my vector is 0 and it expects it to have a size. --------- Robert Dailey
