NAME
ibv_req_notify_cq - request completion notification on a completion
queue (CQ)
SYNOPSIS
#include <infiniband/verbs.h>
int ibv_req_notify_cq(struct ibv_cq *cq, int solicited_only);
DESCRIPTION
ibv_req_notify_cq() requests a completion notification on the comple-
tion 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 success-
ful receive completions, or any successful send completion is unso-
licited.
RETURN VALUE
ibv_req_notify_cq() returns 0 on success, or the value of errno on
failure (which indicates the failure reason).
