The following call will deletethe first ULIP interface from the list of network interfaces:<pre> ulipDelete (0); /* unit number */</pre>Up to NULIP(2) units may be created.<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./if_ulip.html#top">if_ulip</a></b>, <i>VxWorks Programmer's Guide: VxSim</i><hr><a name="ulipInit"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>ulipInit</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>ulipInit</i>( )</strong> - initialize the ULIP interface (VxSim)</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS ulipInit ( int unit, /* ULIP unit number (0 - NULIP-1) */ char * myAddr, /* IP address of the interface */ char * peerAddr, /* IP address of the remote peer interface */ int procnum /* processor number to map to ULIP interface */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine initializes the ULIP interface and sets the Internetaddress as a function of the processor number.<p></blockquote><h4>RETURNS</h4><blockquote><p>OK, or ERROR if the device cannot be opened or there isinsufficient memory.<p></blockquote><h4>ERRNO</h4><blockquote><p>S_if_ul_INVALID_UNIT_NUMBER<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./if_ulip.html#top">if_ulip</a></b>, <i>VxSim User's Guide </i><hr><a name="ulattach"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>ulattach</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>ulattach</i>( )</strong> - attach a ULIP interface to a list of network interfaces (VxSim)</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS ulattach ( int unit /* ULIP unit number */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine is called by <b><i><a href="./if_ulip.html#ulipInit">ulipInit</a></i>( )</b>.

Because there is no simple way for the caller to assertain the unit number of the interface in use, all unit numbers are looped over and each receives the ioctl. Possible values for the debug flag are discussed above in this file, although all thelevels have not been implemented.<p>This is not the right place to put this function (user callable routineswould be more appropriately placed in <b>simLib.h</b>). Because of the requirement to use both Sun structures (to bundle ioctl data) and VxWorks structures (ul_softc), and given the same requirements when calling the FIOSETUSED ioctl, this seems the best place to put it.<p></blockquote><h4>RETURNS</h4><blockquote><p>OK or ERROR if the ioctl fails</blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./if_ulip.html#top">if_ulip</a></b></body></html>⌨️ 快捷键说明
