curs_beep(3) UNIX Programmer's Manual curs_beep(3)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 termi-
nal, 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, 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.
