IBV_REQ_NOTIFY_CQ(3)	Libibverbs Programmer's Manual	  IBV_REQ_NOTIFY_CQ(3)

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).

NOTES
       The request for notification is "one shot."  Only one completion	 event
       will be generated for each call to ibv_req_notify_cq().
