curs_beep(3X) curs_beep(3X)
NAME
beep, flash - curses bell and screen flash routines
SYNOPSIS
#include <curses.h>
int beep(void);
int flash(void);
DESCRIPTION
The beep and flash routines are used to alert the terminal user. The routine beep sounds an audible
alarm on the terminal, if possible; otherwise it flashes the screen (visible bell). The routine
flash flashes the screen, and if that is not possible, sounds the alert. If neither alert is possi-ble, possible,
ble, nothing happens. Nearly all terminals have an audible alert (bell or beep), but only some can
flash the screen.
RETURN VALUE
These routines return OK if they succeed in beeping or flashing, ERR otherwise.
EXTENSIONS
SVr4's beep and flash routines always returned OK, so it was not possible to tell when the beep or
flash failed.
PORTABILITY
These functions are described in the XSI Curses standard, Issue 4. Like SVr4, it specifies that they
always return OK.
