On page 5: > To find the index of an event, the application must mask the current tail index with the size mask of the ring. This commonly looks something like the below: unsigned head; head = cqring→head; read_barrier(); if (head != cqring→tail) { struct io_uring_cqe *cqe; unsigned index; index = head & (cqring→mask); cqe = &cqring→cqes[index]; /* process completed cqe here */ ... /* we've now consumed this entry */ head++; } cqring→head = head; write_barrier(); Am I misunderstanding, or is "current tail index" supposed to be "current head index?"
