Second link in google for 'scanf':


But... if my experience is a guide, you will be sorry you ever heard of scanf. It's not a very robust way to parse input.

Aloha from Honolulu,
I'm trying to use scanf in a program and reading about it I found that it is supposed to reference __fmt string, which is supposed to reside in program memory. I spent a coup[le of hours with Google and the AVR-libc reference, but could find no other information on __fmt string. Can someone explain it to me? How is it composed and where would it reside?
Thanks Very Much,
