<H2>NAME</H2><PRE>
<B>beep</B>, <B>flash</B> - <B>curses</B> bell and screen flash routines
</PRE>
<H2>SYNOPSIS</H2><PRE>
<B>#include</B> <B><curses.h></B>
<B>int</B> <B>beep(void);</B>
<B>int</B> <B>flash(void);</B>
</PRE>
<H2>DESCRIPTION</H2><PRE>
The <B>beep</B> and <B>flash</B> routines are used to alert the terminal
user. The routine <B>beep</B> sounds an audible alarm on the
terminal, if possible; otherwise it flashes the screen
(visible bell). The routine <B>flash</B> flashes the screen, and
if that is not possible, sounds the alert. If neither
alert is possible, nothing happens. Nearly all terminals
have an audible alert (bell or beep), but only some can
flash the screen.
</PRE>
<H2>RETURN VALUE</H2><PRE>
These routines return <B>OK</B> if they succeed in beeping or
flashing, <B>ERR</B> otherwise.
</PRE>
<H2>EXTENSIONS</H2><PRE>
SVr4's beep and flash routines always returned <B>OK</B>, so it
was not possible to tell when the beep or flash failed.
</PRE>
<H2>PORTABILITY</H2><PRE>
These functions are defined in the XSI Curses standard,
Issue 4. Like SVr4, it specifies that they always return
<B>OK</B>.
