Hi.
There isn't any way to know if there are any CQEs in the CQ.
Destroying a CQ which has completions should create seg fault (unless
you have another thread that try to use this CQ ...)

Hi,
Is there any way to figure out that a cq does not have any pending
completion entries and thus
is safe to call ibv_destroy_cq. Or is it ok to call destroy
regardless of whether there are completion
entries? I am seeing a seg fault in ibv_poll_cq if I adopt the
latter approach.
Thanks
Ganesh
