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.
