    Lightbulb Backspace

    Hi,

    maybe I'm stupid, but i was trying to find on the Google how to do a backspace. In C-program I want to load some TXT-file and delete f.e. last 20chars. I tried \b but it didn't work.

    Can anyone help me?

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    You might start by showing your code so we know how you are trying to accomplish your goals. In any case, the simple (possibly not correct in your case) answer is to move your pointer to the end of the string minus 20 characters, and then insert a NUL ('\0') byte.
    Sometimes, real fast is almost as good as real time.
