These events are divided intotwo WindView classes. The <b>NET_CORE_EVENT</b> class indicates events directlyrelated to data transfer. All other events (such as memory allocation andAPI routines) use the <b>NET_AUX_EVENT</b> class. Within each class, events areassigned one of eight priority levels. The four highest priority levels (EMERGENCY, ALERT, CRITICAL, and ERROR) indicate the occurrence of errors and the remaining four (WARNING, NOTICE, INFO, and VERBOSE) provide progressively more detailed information about the internal processing in the network stack. <p></blockquote><h4>USER INTERFACE</h4><blockquote><p>If WindView support is included, the <b>wvNetStart( )</b> and <b>wvNetStop( )</b> routines will enable and disable event reporting for the network stack. The startroutine takes a single parameter specifying the minimum priority level forall network components. That setting may be modified with the <b><a href="./wvNetLib.html#wvNetLevelAdd">wvNetLevelAdd</a>( )</b> and <b><a href="./wvNetLib.html#wvNetLevelRemove">wvNetLevelRemove</a>( )</b> routines. Individual events may be included or removedwith the <b><a href="./wvNetLib.html#wvNetEventEnable">wvNetEventEnable</a>( )</b> and <b><a href="./wvNetLib.html#wvNetDisable">wvNetDisable</a>( )</b> routines.<p>The <b><a href="./wvNetLib.html#wvNetAddressFilterSet">wvNetAddressFilterSet</a>( )</b> and <b><a href="./wvNetLib.html#wvNetPortFilterSet">wvNetPortFilterSet</a>( )</b> routines provide further screening for some events.<p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><p></blockquote><h4>SEE ALSO</h4><blockquote><p><p><i>WindView for Tornado User's Guide </i><hr><a name="wvNetEnable"></a><p align=right><a href="rtnIndex.htm"><i>OS Libraries : Routines</i></a></p></blockquote><h1>wvNetEnable( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong>wvNetEnable( )</strong> - begin reporting network events to WindView</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>void wvNetEnable ( int priority /* minimum priority, or 0 for default of */ /* WV_NET_VERBOSE */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine activates WindView event reporting for network components,after disabling all events with a priority less than <i>level</i>.
