    curs_beep(3x)                    Library calls                   curs_beep(3x)

## NAME

           beep, flash - ring the (visual) bell of the terminal with curses

## 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.
