Where can I find the source code for all the C standard libraries?

I'm looking for the whole source code of all the C standard libraries. That said, I'm looking for the source code of stdio.h, stdlib.h, string.h, math.h, etc... I would like to see how they were created. I think that it depends from platform to platform, but Linux or Windows one will be welcomed.

If you want the actual implementations, as everyone else has assumed you don't, many Linux distributions currently use glibc to implement the C standard library. Common alternatives include musl libc, diet libc, uClibc-ng, and Bionic

Sorry for your problem. Most of the responses you are getting are unnecessarily self complicated for nothing. Its quite obvious what you want: The source codes for all the functions contained in the standard C library; And whose lumps include (of course) stdio.h, conio.h among others. Well, you can get them around and as one zip file right here:

Good luck. Love C.

PJ Plauger wrote a book about the standard C library. Includes references from the (now dated) standard, and source code.

Microsoft Visual Studio generally has the system headers under <InstallDir>\VC\include, and the source, if installed, is under <InstallDir>\VC\crt\src.

Whether its installed with an IDE or you have installed explicitly, you have to look in the directory "Include" in respective location.

Ex: I use MinGW. So, I would go to

c:/MinGW/include to find those header files. Similarly, for an IDE (say Dev-cpp), you need to go to c:/dev-cpp/include.
