</PRE>
<H2>NAME</H2><PRE>
       <STRONG>beep</STRONG>, <STRONG>flash</STRONG> - <STRONG>curses</STRONG> bell and screen flash routines


</PRE>
<H2>SYNOPSIS</H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</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>.
