Re: [avr-gcc-list] scanf and __fmt string

[Roger Furer]

Aloha from Honolulu,
Thanks, but there isn't much info on the format string itself.  How is 
it structured, what does it look like, where is it placed?  Is it just 
the bit inside the parentheses following the scanf statement?  "scanf( 
here? );"  I am under the impression that it is somewhere seperate and 
is reffered to by all the scanf statements in the program.  Please 
correct me if that is wrong.
Thanks,
Roger Furer
