The network task executes andremoves routines that were added to the job queue. This facility is usedby network interfaces in order to have interrupt-level processing attask level.<p>The routine <b><i><a href="./netLib.html#netLibInit">netLibInit</a></i>( )</b> initializes the network and spawns the networktask <b><i><a href="./netLib.html#netTask">netTask</a></i>( )</b>. This is done automatically when the configurationmacro <b>INCLUDE_NETWORK</b> is defined.<p>The routine <b><i><a href="./usrLib.html#netHelp">netHelp</a></i>( )</b> in <b><a href="./usrLib.html#top">usrLib</a></b> displays a summary of the network facilitiesavailable from the VxWorks shell.<p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><b>netLib.h</b><p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./netLib.html#top">netLib</a></b>, <b><a href="./routeLib.html#top">routeLib</a></b>, <b><a href="./hostLib.html#top">hostLib</a></b>, <b><a href="./netDrv.html#top">netDrv</a></b>, <b><i><a href="./usrLib.html#netHelp">netHelp</a></i>( )</b>, <i>VxWorks Programmer's Guide: Network</i><hr><a name="netLibInit"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>netLibInit</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>netLibInit</i>( )</strong> - initialize the network package</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS netLibInit (void)</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This creates the network task jobqueue, and spawns the network task <b><i><a href="./netLib.html#netTask">netTask</a></i>( )</b>.
