.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,
|
|
.B ibv_resize_cq()
|
|
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.
|
|
.SH "RETURN VALUE"
|
|
.B ibv_resize_cq()
|
|
returns 0 on success, or the value of errno on failure (which indicates the failure reason).
|
|
.SH "NOTES"
|
|
.B ibv_resize_cq()
|
|
may assign a CQ size greater than or equal to the requested size.
|
|
The cqe member of
|
|
.I cq
|
|
will be updated to the actual size.
