need to clear the current line output

New to programming, eh?  libncurses finds what TERM is set to, then
looks up the "clear current line" escape sequence for that TERM using
terminfo, then outputs that sequence.  Since you say this is an embedded
app, you already know what TERM is and what the escape sequences are for
that TERM.  You just have to fprintf() (putc(), write(), whatever...)
the right sequence.  "man console_codes" for the standard sequences that
work on TERM=linux (almost all of those work on TERM=xterm as well,
IIRC) and you want to search for "erase".  HTH,

Why do you want to avoid curses, and not go the standard way ?

if the line is 80 chars long, but writing the last character will wrap to
next line then write a carriage-return "\r" then 79 spaces, then another
carriage-return "\r".

   If it's embedded, there presumably can be no question about what
   control sequences are needed to do the job.

   The vast majority of terminals support the ANSI codes, in which
   clear to end of line is ESC [ K.
