[Hi Paul, excellent post! I wrote a Reserve\_PopSlot function that closely resembles Reserve\_EmplaceSlot and added some tests. SPSC, MPSC, SPMC all work great, however I'm running into an issue with MPMC consumer thinking that the queue is empty because cIndices.mUnwrappedPushIndex == cIndices.mUnwrappedPopIndex but mSize is not 0. Have you experienced this?... If you send me your email I can respond with my implementation of Reserve\_PopSlot. Thank you!](https://hashnode.com/posts/c-lock-free-queue-part-ii/651a5e0e0b40966cba661f63/comment/67fd3ea08052c5351da22005)
