[dpdk-dev] Walk through a given mbuf-pool elements

[Vithal S Mohare]

Hi Konstantin,

Thanks for the reply.
I was trying to find more intuitive one compare to rte_mempool_obj_iter().  Once mempool is created with objects, shouldn't we able to walk-through by just passing 'mp' object and avoiding other params like vaddr, elt_size etc.   For now, I could use callback called during mempool creation itself.


Thanks,
-Vithal

Not sure why rte_mempool_obj_iter() wouldn't work for you?
It just walks through all elements of the pool and for ach calls a user provided callback.
Nothing else.
