Miscellaneous Library Functions                     curs_beep(3X)



NAME
     beep, flash - curses bell and screen flash routines

SYNOPSIS
     #include 

     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 ter-
     minal, 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  possi-
     ble,  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.
