CURS_BEEP(3CURSES) Curses Library Functions CURS_BEEP(3CURSES)


NAME


curs_beep, beep, flash - curses bell and screen flash routines

SYNOPSIS


cc [ flag ... ] file ... -lcurses [ library ... ]
#include <curses.h>

int beep(void);


int flash(void);


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.
