Following is my supplementary explanation of this: First, the APIs to be changed are: 1. rte_ring_mp_enqueue 2. rte_ring_sp_enqueue 3. rte_ring_enqueue Second, Let's use an example to explain this: 1. We call API in form: rte_ring_enqueue(r, obj). 2. Current function header indicates that we will have ring[idx] = *obj. 3. However, this is not the case, what we eventually have is: ring[idx] = obj. So I think the current function header is misleading or maybe the implementation of above three functions need to be changed. > Honnappa, Konstantin, Olivier ? > > > > > Fixes: af75078fece3 ("first public release") > > Cc: stable@dpdk.org > > > > Signed-off-by: Feifei Wang <feifei.wang2@arm.com> > > Reviewed-by: Ruifeng Wang <ruifeng.wang@arm.com> > > --- > > lib/librte_ring/rte_ring.h | 6 +++--- > > 1 file changed, 3 insertions(+), 3 deletions(-) > > > > diff --git a/lib/librte_ring/rte_ring.h b/lib/librte_ring/rte_ring.h > > index da17ed6d7..418536b61 100644 > > --- a/lib/librte_ring/rte_ring.h > > +++ b/lib/librte_ring/rte_ring.h > > @@ -276,7 +276,7 @@ rte_ring_enqueue_bulk(struct rte_ring *r, void * > const *obj_table, > > * @param r > > * A pointer to the ring structure. > > * @param obj > > - * A pointer to the object to be added. > > + * A pointer (object) to be added. > > > -- > David Marchand

When you say function header, I am assuming you are talking about the documentation. IMO, the current documentation does not convey any details of the implementation. It is talking about what is expected from the user. > 3.

When enqueue one element to the ring, the param "obj" should be the object to be added into the ring. The object is of type void*.
