Ring Buffers and Circular Data Structures Questions

Discuss implementation and usage of ring buffers and other circular data structures in resource constrained systems. Topics include head and tail pointer management, modulo arithmetic or power of two masking, detection of full and empty conditions, zero copy patterns, and interactions with direct memory access. Cover single producer single consumer and multi producer patterns, lockless and wait free strategies, atomicity and memory ordering considerations, alignment and padding for cache friendliness, and recovery strategies for corrupted indices.
