The beep and flash routines are used to alert the terminal user. The routine beep sounds the audible alarm on the terminal, if possible. If an audible alarm is not possible, the routine flashes the screen (visible bell), if possible.
The routine flash flashes the screen, and if that is not possible, sounds the audible alarm.
If neither an audible or visual signal is possible, these routines produce
no results. Nearly all terminals have an audible signal (bell or beep), but
only some can flash the screen.
The header file
<curses.h>
automatically
includes the header file
<stdio.h>.
These routines always return
OK.
