+ * The rbb is the ring buffer which is composed with many blocks. It is different from the ring buffer.
+ * The ring buffer is only composed with chars. The rbb put and get supported zero copies. So the rbb
+ * is very suitable for put block and get block by a certain order. Such as DMA block transmit,
+ * communicate frame send/recv, and so on.
