Greetings,

Say I want to read a file line by line so I used fgets(). And I want
to parse strings from each line of the file, I used sscanf(). But
there's a strange problem that each time I run the program, sscanf()
cannot read in first line of file correctly. It always appends a
character at the end of last string that's been parsed. I am working
on HP-UX using cc. Anybody has any clue?

Thanks a bunch!

Post a small, reasonably complete, preferably compilable piece of code
showing the problem. Without that, it's a bit like reading your fortune
off tea leaves.

-nrk.

Please post the smallest compilable piece of code which exhibits the
problem. The problem could be that fgets() keeps the newline while
sscanf() doesnt. It would be quite difficult to comment without
getting something more solid to digest.

Post a small example of your code. We're not telepathic... by the way,
whats the "extra character" ? 0x0d or 0x0a by any chance?
