有没有一种方法可以获取电池信息(状态，插入状态等)，而无需在Linux上读取proc/sys文件? [英] Is there a way to get battery info (status, plugged in, etc) without reading a proc/sys file on linux?

问题描述

我想获取有关Linux上C语言中电池的信息.我不想要读取或解析任何文件！ acpi/内核或任何其他模块是否有任何低级接口来获取我想要的信息?

I want to get information about the battery in C on linux. I don't want to read or parse any file! Is there any low-level interface to acpi/the kernel or any other module to get the information I want to have?

我已经在网上搜索了，但是每个问题都会得到答案"parse/proc/foo/bar".我真的不想这样做，因为我认为底层接口的更改不会像File那样快.

I already searched the web, but every question results in the answer "parse /proc/foo/bar". I really don't want to do this because I think, low-level interfaces won't change as fast as Files do.

最诚挚的问候.

推荐答案

您可能正在寻找UPower: http://upower.freedesktop.org/

You might be looking for UPower: http://upower.freedesktop.org/

这是台式机环境和移动设备的普遍需求，因此随着时间的推移，出现了许多解决方案.例如，最古老的版本之一是acpid，现在已经过时了.

This is a common need for both desktop environments and mobile devices, so there have been many solutions over time. For example, one of the oldest ones was acpid, which is pretty much obsolete now.

尽管出于代码清晰的原因，我建议使用诸如UPower之类的轻量级抽象，但/proc和(在某种程度上)/sys中的文件被视为Linux内核ABI的一部分，这意味着对其进行更改通常会皱眉.

While I'd recommend using a light-weight abstraction like UPower for code clarity reasons, the files in /proc and (to some extent) /sys are considered part of the Linux kernel ABI, which means that changing them is generally frowned upon.
