<STRONG>beep</STRONG>, <STRONG>flash</STRONG> - <STRONG>curses</STRONG> bell and screen flash routines
|

</PRE>
|
|
<H2>SYNOPSIS</H2><PRE>
|
|
<STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
|
|
|
|
<STRONG>int</STRONG> <STRONG>beep(void);</STRONG>
|
|
<STRONG>int</STRONG> <STRONG>flash(void);</STRONG>

</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <STRONG>beep</STRONG> and <STRONG>flash</STRONG> routines are used to alert the terminal
|
|
user. The routine <STRONG>beep</STRONG> sounds an audible alarm on the
|
|
terminal, if possible; otherwise it flashes the screen
|
|
(visible bell). The routine <STRONG>flash</STRONG> 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 <STRONG>OK</STRONG> if they succeed in beeping or
|
|
flashing, <STRONG>ERR</STRONG> otherwise.
|
|
|
|
|
|
</PRE>
|
|
<H2>EXTENSIONS</H2><PRE>
|
|
SVr4's beep and flash routines always returned <STRONG>OK</STRONG>, so it
|
|
was not possible to tell when the beep or flash failed.
|
|
|
|
|
|
</PRE>
|
|
<H2>PORTABILITY</H2><PRE>
|
|
These functions are described in the XSI Curses standard,
|
|
Issue 4. Like SVr4, it specifies that they always return
|
|
<STRONG>OK</STRONG>.
