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 possible, 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.
