Where is `scanf` implementation source code

cprintfsource

I want to find C source code for scanf implementation on Linux machine. Googling to find scanf implementation does not tell me the way to find it. I tried to find that source code from gcc source tree using ctags and cscope, but I could not find it. Can anybody please tell me where is scanf function definition, i.e. implementation source code?

It's in glibc library scanf.c source

glibc stands for GNU C Library. It is a C standard library implementation. It's not a part of the compiler, because you might have different implementations of it (like Microsoft C run-time for example) as well as different compilers (like clang).

While Minix has been suggested as one OS to study, another is Unix Sixth Edition via the Lions' Commentary.

Sixth Edition Unix is quite small by today's standards and the Lions' commentary on it is considered to be one of the best set of notes for learning the Unix operating system. For the longest time, it was only available as a multi-generation photocopy, but thankfully it has been reprinted and should be available from your favourite online book seller.

Grep Source Code – How to Grep Without Catching Comments

You can try a naive approach to match non-comments like this:

 $ egrep -v "^(//|/\*| \*)" sourcecode

This will only inverse match against prefixed comments - that is lines starting with either //, /*, * or */ - and hence it'll not leave out blocks that are commented out with the /* and */ pair.
