curs_beep(3X) Library calls curs_beep(3X) NAME beep, flash - ring the (visual) bell of the terminal with curses 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; oth- erwise 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 audi- ble 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 possi- ble to tell when the beep or flash failed. PORTABILITY These functions are described in X/Open Curses, Issue 4. Like SVr4, it specifies that they always return OK. SEE ALSO curses(3X) ncurses 6.5 2024-04-20 curs_beep(3X)
