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.

DESCRIPTION

       The beep and flash routines are used to alert the terminal user. The routine beep sounds the audible alarm on the terminal, if possible. If
       an audible alarm is not possible, the routine flashes the screen (visible bell), if possible.

       The routine flash flashes the screen, and if that is not possible, sounds the audible alarm.

       If neither an audible or visual signal is possible, these routines produce no results. Nearly all terminals have an audible signal (bell or
       beep), but only some can flash the screen.

NOTES

       The header file <curses.h> automatically includes the header file <stdio.h>.

RETURN VALUES

       These routines always return OK.
