35 What is a circular buffer?
38 First of all, what is a circular buffer? A circular buffer is a buffer of
42 buffer.
45 the buffer.
47 Typically when the tail pointer is equal to the head pointer, the buffer is
48 empty; and the buffer is full when the head pointer is one less than the tail
53 indices should be wrapped to 0 when they reach the end of the buffer, thus
54 allowing an infinite amount of data to flow through the buffer.
