# bus\_generic\_detach.9

`bus_generic_detach` — 总线 `DEVICE_DETACH` 的通用实现

## 名称

`bus_generic_detach`

## 概要

```c
#include <sys/param.h>
#include <sys/bus.h>

int
bus_generic_detach(device_t dev)
```

## 描述

此函数提供 [DEVICE\_DETACH(9)](/man/man9/device_detach.9.md) 方法的实现，可供大多数总线代码使用。它使用 bus\_detach\_children(9) 从所有子设备分离驱动程序，让它们有机会否决分离请求。如果 `bus_detach_children` 成功，`bus_generic_detach` 调用 [device\_delete\_children(9)](/man/man9/device_delete_children.9.md) 删除所有子设备。

## 返回值

成功时返回零，否则返回适当的错误。

## 参见

## 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/bus_generic_detach.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.
