You would like to download glibc source and then start looking for whatever you
want...

Alternatively, you can look at the source of printk which is similar(not equal) to printf.
It does not do all the things done by printf but the basic idea is the same.
http://lxr.linux.no/source/kernel/printk.c#L407
Formatting method is quite similar i.e vsprintf(), But to write to the screen,
For printf, In UNIX everything is file so writing to STDOUT will write in screen write(1, ...).
printk uses different method (circular buffer).
