# VFS\_VGET.9

`VFS_VGET` — 将 inode 号转换为 vnode

## 名称

`VFS_VGET`

## 概要

```c
#include <sys/param.h>
#include <sys/mount.h>
#include <sys/vnode.h>

int
VFS_VGET(struct mount *mp, ino_t ino, int flags, struct vnode **vpp)
```

## 描述

`VFS_VGET` 从（挂载点，inode 号）元组查找或创建一个 vnode。

其参数为：

**`mp`** 挂载点。

**`ino`** 表示该文件的 inode。这是文件系统在首次创建 vnode 时分配的唯一编号。

**`flags`** 传递给 [vget(9)](/man/man9/vget.9.md) 的附加锁定标志。

**`vpp`** vnode 的返回参数。

这是一个可选的文件系统入口点，主要供 NFS 服务器使用，但许多文件系统在 [VOP\_LOOKUP(9)](/man/man9/vop_lookup.9.md) 及类似函数中内部使用它。

如果文件系统不支持此调用，则应返回 `EOPNOTSUPP`。

关于规范示例，请参见 **sys/ufs/ffs/ffs\_vfsops.c** 中的 `ffs_vget`。

## 参见

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/vfs_vget.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.
