NAME
       beep, flash - activate audio-visual alarm

SYNOPSIS
       cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib 
       -R /usr/xpg4/lib -lcurses [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int beep(void);

       int flash(void);

DESCRIPTION
       The  beep()  and  flash()  functions  produce an audio and visual alarm on the terminal, respectively.  If the terminal has the capability,
       beep() sounds a bell or beep and  flash() flashes the screen.  One alarm is substituted for another if the terminal does  not  support  the
       capability  called  (see   terminfo(4)  bel  and  flash capabilities). For example, a call to beep() for a terminal without that capability
       results in a flash.

RETURN VALUES
       These functions always return OK.

ERRORS
       None.
