Macros
#define	CONFIG_CHUNK_NUM_MAX   (4)
	The maximum number of chunks that can be stored in a Chunked Ringbuffer.

Typedefs
typedef void(*	crb_foreach_callback_t) (void *ctx, uint8_t *bytes, size_t len)
	Callback function for crb_chunk_foreach.

Functions
void	crb_init (chunk_ringbuf_t *rb, void *buffer, size_t len)
	Initialize a Chunked Ringbuffer.
static bool	crb_start_chunk (chunk_ringbuf_t *rb)
	Start a new chunk on the ringbuffer.
static bool	crb_add_byte (chunk_ringbuf_t *rb, uint8_t b)
	Insert a byte into the current chunk.
bool	crb_add_bytes (chunk_ringbuf_t *rb, const void *data, size_t len)
	Insert a number of bytes into the current chunk.
bool	crb_end_chunk (chunk_ringbuf_t *rb, bool valid)

bool	crb_add_chunk (chunk_ringbuf_t *rb, const void *data, size_t len)
	Add a complete chunk to the Ringbuffer.
bool	crb_get_chunk_size (chunk_ringbuf_t *rb, size_t *len)
	Get the size of the first valid chunk.
bool	crb_peek_bytes (chunk_ringbuf_t *rb, void *dst, size_t offset, size_t len)
	Get a number of bytes from the first valid chunk without consuming it.
bool	crb_consume_chunk (chunk_ringbuf_t *rb, void *dst, size_t len)
	Remove a chunk from the valid chunk array.
bool	crb_chunk_foreach (chunk_ringbuf_t *rb, crb_foreach_callback_t func, void *ctx)
	Execute a callback for each byte in the first valid chunk The callback function may be called twice if the chunk is non-continuous.
