.SH "DESCRIPTION"
.B ibv_resize_cq()
resizes the completion queue (CQ)
.I cq
to have at least
.I cqe
entries.
.I cqe
must be at least the number of unpolled entries in the CQ
.I cq\fR.
If
.I cqe
is a valid value less than the current CQ size,

may not do anything, since this function is only guaranteed to resize
the CQ to a size at least as big as the requested size.

returns 0 on success, or the value of errno on failure (which indicates the failure reason).
