Dynamic output updation on a command line interface

Hi

I am eager to know how to print the output on a terminal screen similar to the one that of the 'top' command.

What I mean to say is .. dynamic updation of the existing output on terminal window.

A small c program or reference to appropriate resources is expected ....

I think you want to check out ncurses (or *curses, or whatever is appropriate for termio on your platform). ANSI escape sequences is also of interest :)

Seems ANSI escape sequences are really tough to program with .. might be the crude way of doing things ??

@codingfreak, I agree with tinkertim; ncurses is the way to go. It's also a pretty fun API to work with.

@codingfreak: I linked to escape sequences so you could see just how much pain ncurses (and others) save you.

Yeah guys I do agree with you ncurse really does solve the pain ...

Ncurses (Unix-only I think) or PDCurses (portable) is the way to go.
