# pthread\_suspend\_all\_np.3

`pthread_suspend_all_np` — 挂起所有活动线程

## 名称

`pthread_suspend_all_np`

## 库

Lb libpthread

## 概要

`#include <pthread_np.h>`

```c
void
pthread_suspend_all_np(void);
```

## 描述

`pthread_suspend_all_np()` 函数会使所有活动线程挂起。唯一的例外是当前线程，即调用 `pthread_suspend_all_np()` 函数的线程。

在挂起的线程被恢复之前，`pthread_suspend_all_np()` 函数的调用者使用任何非异步信号安全函数都是不安全的，除非采取相应措施确保所有线程都在安全点挂起，但 [pthread\_resume\_all\_np(3)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man3/pthread_resume_all_np.3.md) 例外。

# 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/pthread/pthread_suspend_all_np.3.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.
