C/C++: where can I look at the code for built in functions?

[Special K]

I was just curious to see the code that the built in functions such as fopen, printf, etc. contain. I looked at the appropriate header files but all I could find were the prototypes. Where should I look?

Get the source for the GNU compiler. You'll be able to find it there.

On certain compilers you can find some of it in the .CPP versions of the .H files.

Get the source for the GNU C libraries, not the compiler.

Oops, yes of course...
