| .SH "DESCRIPTION" |
| .B ibv_resize_cq() |
| resizes the completion queue (CQ) |
| .I cq |
| to have at least |
| .I cqe |
| entries. |

| must be at least the number of unpolled entries in the CQ |
| .I cq\fR. |
| If |

| 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). |

| .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. |
