IBV_REQ_NOTIFY_CQ(3) Libibverbs Programmer’s Manual IBV_REQ_NOTIFY_CQ(3)
ibv_req_notify_cq - request completion notification on a
completion queue (CQ)
#include <infiniband/verbs.h>
int ibv_req_notify_cq(struct ibv_cq *cq, int solicited_only);
ibv_req_notify_cq() requests a completion notification on the
completion queue (CQ) cq.
Upon the addition of a new CQ entry (CQE) to cq, a completion
event will be added to the completion channel associated with the
CQ. If the argument solicited_only is zero, a completion event is
generated for any new CQE. If solicited_only is non-zero, an
event is only generated for a new CQE with that is considered
“solicited.” A CQE is solicited if it is a receive completion for
a message with the Solicited Event header bit set, or if the
status is not successful. All other successful receive
completions, or any successful send completion is unsolicited.
ibv_req_notify_cq() returns 0 on success, or the value of errno on
failure (which indicates the failure reason).
The request for notification is “one shot.” Only one completion
event will be generated for each call to ibv_req_notify_cq().
