Reset(empty) the ringbuffer.

NOT thread safe.

uint32_t Raul::RingBuffer::peek	(	uint32_t	size,
		void *	dst
	)			[inline]

Peek at the ringbuffer (read w/o advancing read pointer).

Note that a full read may not be done if the data wraps around. Caller must check return value and call again if necessary, or use the full_peek method which does this automatically.

References _buf, and _size.

uint32_t Raul::RingBuffer::read	(	uint32_t	size,
		void *	dst
	)			[inline]

Read from the ringbuffer.

Note that a full read may not be done if the data wraps around. Caller must check return value and call again if necessary, or use the full_read method which does this automatically.
