60 The <STRONG>beep</STRONG> and <STRONG>flash</STRONG> routines are used to alert the terminal user. The
61 routine <STRONG>beep</STRONG> sounds an audible alarm on the terminal, if possible; oth-
62 erwise it flashes the screen (visible bell). The routine <STRONG>flash</STRONG> flashes
63 the screen, and if that is not possible, sounds the alert. If neither
64 alert is possible, nothing happens. Nearly all terminals have an audi-
65 ble alert (bell or beep), but only some can flash the screen.

69 These routines return <STRONG>OK</STRONG> if they succeed in beeping or flashing, <STRONG>ERR</STRONG>

74 SVr4's beep and flash routines always returned <STRONG>OK</STRONG>, so it was not possi-
75 ble to tell when the beep or flash failed.

79 These functions are described in the XSI Curses standard, Issue 4.
80 Like SVr4, it specifies that they always return <STRONG>OK</STRONG>.
