I am quite interested on how the printf function works really under the code to print the characters on display. I actually got stuck at __vfprintf_internal function which i am not able to find the definition through tags. BTW, is this the actual function called internally by printf ? Can you please help me on this code learning ? Also please suggest me the right tools/method to traverse through the source code... Thanks, Eswar
