curs_beep(3x)                                                    curs_beep(3x)




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.
