libc source location - for download or online viewing?
提问by ValenceElectron
Sorry I know this is stupid but where is linux libc source code available? What I downloaded from GNU didn't seem to be what I wanted, specifically I could find nothing in the pthreads function family.
抱歉，我知道这很愚蠢，但是 linux libc 源代码在哪里可用？我从 GNU 下载的似乎不是我想要的，特别是我在 pthreads 函数系列中找不到任何东西。
Is there an online (hypertexted cross-referenced) version somewhere?
某处是否有在线（超文本交叉引用）版本？

Most linuxes use a libc version named glibc.
大多数 linux 使用名为glibc.
The LXR (online cross-reference system) for glibc is e.g. here http://koala.cs.pub.ro/lxr/glibc/for 2.9 version(link is broken). I must say that something may be not lxr'ed because some sources are generated in the build process, for example - as i can remember - wrappers around a system calls.
glibc 的 LXR（在线交叉参考系统）例如在这里http://koala.cs.pub.ro/lxr/glibc/对于 2.9 版本（链接已损坏）。我必须说有些东西可能不是 lxr'ed，因为某些源是在构建过程中生成的，例如 - 我记得 - 系统调用的包装器。
Pthreads are in nptl/folder. Right link to libc sources is http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.bz2(or change 2.14 to your version)
Pthreads 在nptl/文件夹中。libc 源的正确链接是http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.bz2（或将 2.14 更改为您的版本）
Update: After closing of koala's lxr, there are:
更新：关闭考拉的 lxr 后，有：
Metager with glibc: http://code.metager.de/source/xref/gnu/glibc/(Served with Sun's OpenGrok, which was originally used to generate online x-ref for Solaris/OpenSolaris)Google code search (I know that it was closed; but I also know it's other version which is up):
http://code.google.com/codesearchand try to search something glibc-specific
Metager with glibc：http://code.metager.de/source/xref/gnu/glibc/（与 Sun 的 OpenGrok 一起使用，最初用于为 Solaris/OpenSolaris 生成在线 x-ref）Google 代码搜索（我知道它已关闭；但我也知道它是另一个版本）：
http://code.google.com/codesearch并尝试搜索特定于 glibc 的内容
UPD (march 2013) They killed codesearch again:
UPD（2013 年 3 月）他们再次杀死了 codesearch：
404. That's an error.The requested URL /codesearch was not found on this server. That's all we know.
404. That's an error.在此服务器上找不到请求的 URL /codesearch。我们知道的就这些。
UPD 2017
UPD 2017
Metager with glibc: http://code.metager.de/source/xref/gnu/glibc/There is online git by glibc authors: https://sourceware.org/git/?p=glibc.git(tree is browserable at https://sourceware.org/git/?p=glibc.git;a=tree)
Glibc git is mirrored to github (which has some searching functions) https://github.com/bminor/glibcBuildroot 2018.05 notably uses this mirror.
There is search like google's codesearch in all debian packages: https://codesearch.debian.net/. It can search in glibc sources by "package:glibc request" request and also have file browser: http://sources.debian.net/src/glibc/
带 glibc 的 Metager：http://code.metager.de/source/xref/gnu/glibc/glibc 作者有在线 git：https: //sourceware.org/git/ ?p =glibc.git（树可在https://sourceware.org/git/?p=glibc.git;a=tree 浏览）
Glibc git 被镜像到 github（它有一些搜索功能）https://github.com/bminor/glibcBuildroot 2018.05特别使用了这个镜像。
在所有 debian 包中都有类似 google 的 codesearch 的搜索：https://codesearch.debian.net/ 。它可以通过“package:glibc request”请求在 glibc 源代码中搜索，也可以有文件浏览器：http: //sources.debian.net/src/glibc/

If you're on a Debian-derived system, you can use apt-get source libc6. This will unpack a eglibc-2.12.1directory (version number might differ, of course) in your current working directory, and the pthreads support are in the nptl/directory below that. linuxthreads/is for the older threading style, in case you're an archaeologist.
如果您使用的是 Debian 派生系统，则可以使用apt-get source libc6. 这将eglibc-2.12.1在您当前的工作目录中解压一个目录（当然，版本号可能不同），并且 pthreads 支持位于该nptl/目录下。linuxthreads/用于较旧的线程样式，以防您是考古学家。

Info on the glibc repository: http://sourceware.org/glibc/wiki/GlibcGit
关于 glibc 存储库的信息：http: //sourceware.org/glibc/wiki/GlibcGit
Clone it to get your own copy and search it however you like:
克隆它以获得您自己的副本并根据您的喜好进行搜索：
git clone git://sourceware.org/git/glibc.git
I load it up in an IDE project (using whatever preferred IDE) and the code navigation works quite well to let me find what I'm interested in.
我将它加载到 IDE 项目中（使用任何首选的 IDE），代码导航运行良好，可以让我找到感兴趣的内容。
