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. .SH "SEE ALSO" .BR ibv_create_cq (3) .BR ibv_destroy_cq (3) .SH "AUTHORS" .TP Dotan Barak <dotanb@mellanox.co.il>
