NAME
       bbeeeepp, ffllaasshh - ccuurrsseess bell and screen flash routines

SYNOPSIS
       ##iinncclluuddee <>

       iinntt bbeeeepp((vvooiidd));;
       iinntt ffllaasshh((vvooiidd));;

DESCRIPTION
       The  bbeeeepp  and ffllaasshh routines are used to alert the terminal user.  The
       routine bbeeeepp sounds an audible alarm on the terminal, if possible; oth-
       erwise it flashes the screen (visible bell).  The routine ffllaasshh flashes
       the screen, and if that is not possible, sounds the alert.  If  neither
       alert is possible, nothing happens.  Nearly all terminals have an audi-
       ble alert (bell or beep), but only some can flash the screen.

RREETTUURRNN VVAALLUUEE
       These routines return OOKK if they succeed in beeping  or  flashing,  EERRRR
       otherwise.

EEXXTTEENNSSIIOONNSS
       SVr4's beep and flash routines always returned OOKK, so it was not possi-
       ble to tell when the beep or flash failed.

PPOORRTTAABBIILLIITTYY
       These functions are described in the  XSI  Curses  standard,  Issue  4.
       Like SVr4, it specifies that they always return OOKK.
