Read unfixed length from ringbuf #5

Hi, is it possible to read an unfixed length packet from the ringbuf?

For example, my packet has the format: [ <content: sizeof(size)> ] and its size can not be determined before running. I tried to call rb.read() two times but it seems that those two read() calls will consume two different packets.

rb.read() should read the length of the buffer.
