</blockquote><h1>wvNetEventEnable(&nbsp;)</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  
<p><strong>wvNetEventEnable(&nbsp;)</strong> - activate specific network events</p>

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>STATUS wvNetEventEnable
    (
    int priority,             /* priority level of event */
    int offset                /* identifier within priority level */
    )
</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine allows reporting of a single event within the priority equal 
to <i>level</i>. The activation is overridden if the setting for the entire 
priority level changes. The available priority values are:
<p>
&nbsp;&nbsp;&nbsp;&nbsp;<b>WV_NET_EMERGENCY</b>&nbsp;(1)<br>
&nbsp;&nbsp;&nbsp;&nbsp;<b>WV_NET_ALERT</b>&nbsp;(2)<br>
&nbsp;&nbsp;&nbsp;&nbsp;<b>WV_NET_CRITICAL</b>&nbsp;(3)<br>
&nbsp;&nbsp;&nbsp;&nbsp;<b>WV_NET_ERROR</b>&nbsp;(4)<br>
&nbsp;&nbsp;&nbsp;&nbsp;<b>WV_NET_WARNING</b>&nbsp;(5)<br>
&nbsp;&nbsp;&nbsp;&nbsp;<b>WV_NET_NOTICE</b>&nbsp;(6)<br>
&nbsp;&nbsp;&nbsp;&nbsp;<b>WV_NET_INFO</b>&nbsp;(7)<br>
&nbsp;&nbsp;&nbsp;&nbsp;<b>WV_NET_VERBOSE</b>&nbsp;(8)
<p>
Offset values for individual events are listed in the documentation.
<p>
</blockquote><h4>RETURNS</h4><blockquote><p>
OK, or ERROR for unknown event.

</blockquote><h1>wvNetAddressFilterSet(&nbsp;)</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  
<p><strong>wvNetAddressFilterSet(&nbsp;)</strong> - specify an address filter for events</p>

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>STATUS wvNetAddressFilterSet
    (
    char * pAddress,          /* target address for event comparisons */
    char * pMask,             /* mask value applied to data fields */

    int    direction          /* 0 for input, 1 for output */
    )
</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine activates an additional test that disables certain events
that do not match the specified IP address. The <i>pAddress</i> parameter
provides the test value in dotted-decimal format. The <i>type</i> parameter
indicates whether that address is compared against the source or
destination values, and the <i>direction</i> value identifies whether the 
<i>type</i> is interpreted from the perspective of incoming or outgoing traffic.
The <i>pMask</i> parameter provides a network mask to support testing for a
group of events.

</blockquote><h4>RETURNS</h4><blockquote><p>
OK if filter set, or ERROR otherwise.
