[...] > +_Static_assert(sizeof(struct rte_event) == 16, "Event structure size is not > 16-bytes in size"); Thank you for adding this extra check. We should have more of these. NB: _Static_assert is deprecated in C23 [1], so for forward compatibility, you could use static_assert (which is available in <assert.h>) instead. Nice to have; feel free to ignore this comment.
