What Is Circular Buffer in C?
Circular Buffer Is a Fifo Data Structure That Treats Memory to Be Circular; That Is, the Read/Write Indices Loop Back to 0 After It Reaches the Buffer Length...

In respect to this, what is meant by circular buffer?
A circular buffer, circular queue, cyclic buffer or ring buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end. This structure lends itself easily to buffering data streams.
Secondly, what is a circular buffer and how is it used in real time systems? A circular buffer is a memory allocation scheme where memory is reused (reclaimed) when an index, incremented modulo the buffer size, writes over a previously used location. A circular buffer makes a bounded queue when separate indices are used for inserting and removing data.
Keeping this in consideration, what is ring buffer in C?
Circular buffers (also known as ring buffers) are fixed-size buffers that work as if the memory is contiguous & circular in nature. As memory is generated and consumed, data does not need to be reshuffled – rather, the head/tail pointers are adjusted. When data is added, the head pointer advances.
How do you implement a ring buffer?
There are two common ways of implementing a queue with a ring buffer. One is to use an array as the backing storage plus two indices to the array; read and write. To shift a value from the head of the queue, index into the array by the read index, and then increment the read index.
