Source code of PThread Library?

Question

I am trying to find the source code of pthread library. (I guess its a supposed to be a part of Linux source code)

But somehow can't find any good website that has it.

I like this website: http://lxr.linux.no/#linux+v2.6.34.1/ where I usually find what I need. Somehow pthread source is not searchable. Anyway, I wanted to mention that I need a link to a browsable (and searchable) website like that one.

Websites for browsing linux source can be a matter of personal taste. So all links to the pthread source are welcome.

Most probably I will end up bookmarking all of them, look thru them, and then accept the best answer.

pthreads are implemented on Linux in libc. The usual libc is glibc - the glibc pthreads implementation is called NPTL, and the source is available in gitweb.

Does anyone use pth anymore? I guess so since I'm seeing a coreutils test failure possibly due to lack of pth at [FAIL: test-rwlock1 on 32-bit ARM](https://lists.gnu.org/archive/html/coreutils/2018-02/msg00011.html). – jww Feb 06 '18 at 19:16

You can find the source at both of these links:

http://www.opengroup.org/onlinepubs/009695399/basedefs/pthread.h.html

http://code.google.com/p/pthread-lib/source/browse/trunk/pthread-lib/src/ptl_array_list.c

Oh perfect. That is what I was looking for. But if anyone else comes across more links, please do post. – bits Jul 11 '10 at 19:12
@bits: You could look at this question as well(http://stackoverflow.com/questions/6481291/libc-source-location-for-download-or-online-viewing). osgx provided a link (http://koala.cs.pub.ro/lxr/glibc/) which is also in a cross-reference form. – yaobin Apr 16 '12 at 04:52

the first link is broken :( – nacho4d Apr 19 '12 at 06:50

Did you look at GNU libc?

On my Debian box, I see

I tried to find it after reading your answer. But I can't figure out where to look. I am new to Linux source code stuff. I would appreciate if you could point me to a link. – bits Jul 11 '10 at 18:58

A Google search for "gnu libc source code" (no quotes) will lead you straight to the official site: http://www.gnu.org/software/libc/#Availability – David Z Jul 11 '10 at 19:02

Besides David's helpful answer, there is also source code for libc6 in whichever Linux distro you use -- for me it is as easy as `apt-get source libc6`. – Dirk Eddelbuettel Jul 11 '10 at 19:06

Thanks guys, First of all I didn't know that pthreads is a part of glibc. So... now I know. Secondly, following David's suggestion, I downloaded the linuxthreads tarball from http://ftp.gnu.org/gnu/glibc/ And that is helping me learn better. But I would love it more if I have a website where I can browse all this code. – bits Jul 11 '10 at 19:10
Dirk, Thanks for your suggestion as well. Unfortunately, I am living on windows to learn linux. But I will use that command to get libc6 source as soon as I am on linux env. For now, I am looking for an easy to browse website. – bits Jul 11 '10 at 19:12

Please note that linuxthreads is the old implementation of threads. The new one is called NPTL and should be in the normal glibc tarballs. – ninjalj Jul 11 '10 at 19:14
