liblfds is a highly portable lock-free data structure library written in C. It provides queues, stacks, freelists, ring buffers, hash tables, and more that operate using only atomic operations without mutexes, so no deadlock or priority inversion occurs even when multiple threads access them concurrently. It is distributed without a specific license, close to the public domain, and has no external dependencies, making it easy to include in embedded or kernel-level code.
