    Hey,

    Just working on my assignment and got a little stuck. I've to create a text editor for a unix enviroment. Anyways... one of the commands (Its meant to be like VI I guess ;) ) is to display the document to screen which is easy enough obviously :)

    However... it must display numbered lines. Anyone know if there are any built in libraries to do this with either C(1989 standard) or Unix calls ? Or am I going to have to count each line manually and print off a new number?

    By what means are you displaying the document to screen?
    E.g. are you using ncurses library with output buffering? QT? printf?

    Ok I'll guess that you're trying to copy "less -N filename".

    Built in C library? Short answer, you'll have to manage keeping track of line numbers yourself. Don't know enough about your prog (scrolling/ linewrapping/resizable window?) to say whether this is trivial or not.
