Hello all.
Is there a way to deallocate an rte_ring? Maybe I'm missing something,
but I can't find an API function for that at
http://dpdk.org/doc/api/rte__ring_8h.html
Regards,
Dmitry

Dpdk hasn't API to free ring/memzone/mempool, what's the scene you must
free the ring?

It seems that there are no APIs to free a ring.

Well, I'm writing a packet defragmenting code. I have a data structure
consisting of a rte_hash, a rte_ring and an array allocated with
rte_zmalloc. All these besides the ring can be freed. So looks like I
can't destruct my object after allocating. Strictly speaking, I don't
have to. The need shouldn't arise in normal situation. I just considered
writing allocating/deallocating function pairs and processing all
allocation errors to be a good practice.
Isn't it a bit strange to have rte_hash_free() and not have
rte_ring_free()? What's the reason for this?
Best wishes,
Dmitry
