This method doesn't allocate anything ; you have to allocate the object you want to fill yourself. You can find more details about how to work with rings there: - DPDK Programmer's Guide (Chapter 5 - Ring Library) - DPDK API Documentation for rte_ring.h Both of which are accessible at http://dpdk.org/doc Quite a few sample applications (examples/ directory in the DPDK distribution) also make use of rings, notably the quota_watermark one, so it's also a good place to look at. On a side note, it looks like the API reference page for rte_ring.h is broken? It's missing a lot of functions. I'll look into it if I get a chance. http://dpdk.org/doc/api/rte__ring_8h.html#func-members Cyril
