Under Linux Ncurses _is_ the API for interaction with a terminal.  It is
present on all Linux installations except specially stripped-down
embedded systems.

Linux provides support for any terminal you choose to connect to it.
Terminfo entries already exist for just about every one in existence.
If you want your program to work with whatever your users choose to use
there are two approaches: 

1) Determine what terminal they are using, get the data on it out of the
   terminfo database, and send the correct codes as needed.  In other
   words, duplicate the functionality of Ncurses.

2) Use Ncurses and don't worry about it.

If you are working with an embedded system with which only one type of
terminal will ever be used and the overhead of Ncurses is intolerable
just send the codes.

Under DOS and Windows this "problem" does not exist because choice of
terminals does not exist.

I'd suggest that you look at other options such as S-lang, but you seem
to have an aversion to libraries.
