NAME
       rpma_cq_wait - wait for a completion and ack it


SYNOPSIS
             #include <librpma.h>

             struct rpma_cq;
             int rpma_cq_wait(struct rpma_cq *cq);


DESCRIPTION
       rpma_cq_wait()  waits  for an incoming completion event and acks it. If rpma_cq_wait() succeeds, then all
       available completions should be collected using rpma_cq_get_wc(3) before the next rpma_cq_wait() call.


RETURN VALUE
       The rpma_cq_wait() function returns 0 on success or a negative error code on failure.


ERRORS
       rpma_cq_wait() can fail with the following errors:

       •  RPMA_E_INVAL - cq is NULL

       •  RPMA_E_PROVIDER - ibv_req_notify_cq(3) failed with a provider error

       •  RPMA_E_NO_COMPLETION - no completions available

       •  RPMA_E_SHARED_CHANNEL - the completion event channel is shared and cannot be handled by any particular
          CQ
