Reading record batch from IPC

Hi,

Can anyone clarify how to create an InputStream from the memory biffer in C++?  Which subclass should I use?

L
class InputStream : public virtual arrow::io::FileInterface, public virtual arrow::io::Readable, public std::enable_shared_from_this<InputStream>
Subclassed by arrow::io::internal::InputStreamConcurrencyWrapper< Derived >, arrow::io::RandomAccessFile, arrow::io::StdinStream, arrow::io::TransformInputStream, arrow::io::internal::InputStreamConcurrencyWrapper< BufferedInputStream >, arrow::io::internal::InputStreamConcurrencyWrapper< CompressedInputStream >, arrow::io::SlowInputStreamBase< InputStream >
