Detailed Description

Backward compatibility header for concurrent_queue.

This header provides backward compatibility for code using the old include path. The implementation has been moved to: include/kcenon/thread/concurrent/concurrent_queue.h

Migration Guide

Update your includes from:

#include <kcenon/thread/lockfree/lockfree_queue.h>

To:

#include <kcenon/thread/concurrent/concurrent_queue.h>

And update usage from:

kcenon::thread::lockfree_queue<int> queue;  // Deprecated

To:

kcenon::thread::detail::concurrent_queue<int> queue;  // Correct

Why the change?

The name "lockfree_queue" was misleading because the implementation uses fine-grained locking (mutexes), not true lock-free algorithms. The rename to "concurrent_queue" accurately describes the thread-safe nature without implying lock-free semantics.

For a true lock-free queue, see lockfree_job_queue which uses the Michael-Scott algorithm with hazard pointers.

Deprecated

This header will be removed in a future major version. Use <kcenon/thread/concurrent/concurrent_queue.h> instead.
