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.
