printf() simply sends all its output to the console, as is written in
the ISO C standard.

cprintf() is not defined in the ISO C standard; it's a holdover from
Borland.  Most DJGPP programs that need to access the bottom line of
the screen use direct screen writes (ScreenUpdateLine() or just
_farpokew() through _dos_ds) or the pdcurses library.
