You mean, drawing objects with characters? If you want to draw graphics
on console you'll need SVGAlib.

Everything above you'll find in ncurses. You're using debian, right?
`apt-get install libncurses5-dev` and read the documentation in
/usr/share/doc/libncurses5-dev/html . There's a lot of examples there.

The above are standard C library functions. If you `apt-get install
glibc-doc`, you can find'em in "info libc". But I strongly reccomend the
book by the authors of the language, Kernighan & Ritchie "The C
Programming Language".

To know what headers you should include for a given function, try "man 3
function" or "man 2 function". If you installed the above, this will
work for both ncurses functions and standard C functions.
Hope this helps,
