SYNOPSIS

             #include <librpma.h>

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
