.SH "DESCRIPTION"
.B ibv_create_cq()
creates a completion queue (CQ) with at least
.I cqe
entries for the RDMA device context
.I context\fR.
The pointer
.I cq_context
will be used to set user context pointer of the CQ structure. The argument
.I channel
is optional; if not NULL, the completion channel
.I channel
will be used to return completion events.  The CQ will use the
completion vector
.I comp_vector
for signaling completion events; it must be at least zero and less than
.I context\fR->num_comp_vectors.
.PP
.B ibv_destroy_cq()
destroys the CQ
.I cq\fR.
.SH "RETURN VALUE"
.B ibv_create_cq()
returns a pointer to the CQ, or NULL if the request fails.
.PP
.B ibv_destroy_cq()
returns 0 on success, or the value of errno on failure (which indicates the failure reason).
.SH "NOTES"
.B ibv_create_cq()
may create a CQ with size greater than or equal to the requested
size. Check the cqe attribute in the returned CQ for the actual size.
.PP
.B ibv_destroy_cq()
fails if any queue pair is still associated with this CQ.
