If you want to use NCURSES / CURSES, it's a bit complicated.
Otherwise, just output %c (the character) 0x07, BEL, which
generates an audible bell, or beep.

initscr();

intrflush(stdscr, FALSE);
keypad(stdscr, TRUE);
start_color();
printf("beep: %d\n", beep());
fflush(stdout);
printf("flash: %d\n", flash());
fflush(stdout);
return 0;
