Console in ANSI C or *nix

Sun, 14 May 2006 03:49:31 -0700

How do I
clear the console,
get position where I am on the console,
and set position?

Is it possible to do it in ansi C?
If not, is it possible to do it in C on unix?
If not, is it possible at all?

No -- unix uses ansi c too :)

Yes. use curses library functions. unlike ms-windows, *nix supports hundreds of terminal types and each one has its own way of moving the cursor around the screen. That is why there are no standard ascii c functions to control the cursor. I suppose you could do your own thing with the terminfo.h and associated library, but that would entail pretty low-level programming. There might be another console lib like curses but I don't know of one.

One problem though, I compile with:
gcc -g client.c -lcurses
but it says:
client.c:16:20: curses.h: No such file or directory

I tried to compile with -lncurses too but it didn't work either...

Why is it called curses?
Becouse the include is cursed.

you may have to specify the full path to the curses .h files
gcc -g -I/<path to header files here> client.c -lcurses

also search your hard drive to insure the curses library is installed.

I searched for it and it couldn't be found, so I downloaded it.
Now the hard part is to understand the instructions to install...

Thanks
