# VOP\_REVOKE.9

```

## 描述

`VOP_REVOKE` 将以管理方式撤销对由 `vp` 指定的设备以及通过 make\_dev\_alias(9) 创建的任何别名的访问。打开这些设备的进程对此类设备的进一步文件操作通常会失败。`flags` 必须设置为 `REVOKEALL`，表示所有访问都将被撤销；任何其他值都是无效的。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man9/vop_revoke.9.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
