glibc - Wikipedia
March 20, 2026 - The glibc project was initially written mostly by Roland McGrath, working for the Free Software Foundation (FSF) in the summer of 1987 as a teenager. In February 1988, FSF described glibc as having nearly completed the functionality required by ANSI C. By 1992, it had the ANSI C-1989 and POSIX.1-1990 functions implemented and work was under way on POSIX.2.

Obtaining glibc code can be done via apt-get command. Here's basic process done in terminal, which takes no longer than 5 mins:
- Create
glibc-sourcedirectory withmkdir glibc-sourceandcd glibc-source - run
apt-get source glibc - Once
apt-getis done, you'll have 3 files and one directory,glibc-2.23/,glibc_2.23-0ubuntu3.dsc,glibc_2.23-0ubuntu3.debian.tar.xz,glibc_2.23.orig.tar.xz. The file you want isglibc-2.23/stdlib/atoi.c

Actually found it in the git repo here: https://github.com/lattera/glibc/search?utf8=%E2%9C%93&q=atoi&type=
Leaving this here to help anyone else who might wonder this in the future.

r/C_Programming on Reddit: How to navigate source code of C language/standard?
February 9, 2022 -
Out of curiosity, I really want to dig into the source code implementation of various C features like how is int, function, switch, ... implemented by C. Can you help me get started and point to where the actual source code is located so I can try to understand it?
Also, I want to know if the functions defined by the header files like math.h, stdio.h, ... are actually implemented by C or are they implemented by the compiler (gcc/clang). And where to locate the source code of these? (like where to find source code of qsort for example)
Are there any resources for learning about the internals of the language at this depth (other than the actual source code)?
And, it would really help me if you can expand the answer for the above questions to C++ also. For example, in C++ string contains the actual character array and the length of the array. But where to find the source code of string to see all the things that string does internally.

What you want is to read the sources of a compiler and the C standard library (libc). The two most widely-used compilers are GCC and Clang, and the C library is usually glibc (on Linux, that is). https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git https://github.com/llvm/llvm-project/tree/main/clang/ https://sourceware.org/git/?p=glibc.git

I think you want to look at the two different things: How does the standard library is implemented. You can find the implementation of functions like printf() or malloc() in the libc of your compiler. But be warned there are a lot of macros and "unnecessary" code to maintain cross compatibility between architectures, os and cpp/c. You can find the source code of GNU GCC and Clang online. And how is the language C implemented in a computer. How does a int or a while loop work. If you want to know that you can simply look at the compiled machine code of your program. That are the instructions which are platform specific and will be executed by your processor.
