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.

What are ring buffers used for?

Ring Buffer (or Circular Buffer) is a bounded circular data structure that is used for buffering data between two or more threads.

What is ring buffer in data structure?

August 2022) In computer science, 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. There were early circular buffer implementations in hardware.
