MirOS Manual: beep(3), curs_beep(3), flash(3)


curs_beep(3)        UNIX Programmer's Manual         curs_beep(3)

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 termi-
     nal, 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.
