#include <curses.h>
int beep(

int flash(

DESCRIPTION
The
beep() and
flash() routines are used to signal the terminal user.
The routine
beep() sounds the audible alarm on the terminal, if
possible; if that is not possible, it flashes the screen (visible
bell), if that is possible. The routine
flash() flashes the screen,
and if that is not possible, sounds the audible signal. If neither
signal is possible, nothing happens. Nearly all terminals have an
audible signal (bell or beep), but only some can flash the screen.
RETURN VALUES
These routines always return
OK.
