无锁队列通过CAS操作和chunk机制避免多线程竞争和频繁内存分配,提升性能。ypipe_t和yqueue_t实现单写单读,利用局部性原理复用chunk,减少内存分配开销。flush()函数用于检测队列状态并唤醒对端线程。

size() - returns number of elements in the queue, its value is not guarenteed, as push/pop might be lazy to increment their respective indexes. enqueue() / dequeue() - convenience methods call push()/pop() respectively. The bandwidth performance, measured using the src/q_bandwidth.cpp show...
