Currently the table contains two diskette types:<ul><li> A <i>type</i> of 0 indicates the first entry in the table (3.5" 2HD, 1.44MB);</li><li> A <i>type</i> of 1 indicates the second entry in the table (5.25" 2HD, 1.2MB). </ul><p><p>The <i>fileName</i> parameter is the mount point, e.g., <b>/fd0/</b>.<p></blockquote><h4>NOTE</h4><blockquote><p>Do not attempt to unmount a volume that was mounted with <b><i><a href="./usrFd.html#usrFdConfig">usrFdConfig</a></i>( )</b> using <b><i><a href="./dosFsLib.html#dosFsVolUnmount">dosFsVolUnmount</a></i>( )</b>. <b><i><a href="./usrFd.html#usrFdConfig">usrFdConfig</a></i>( )</b> does not return the <b>DOS_VOL_CONFIG</b> structure required by <b><i><a href="./dosFsLib.html#dosFsVolUnmount">dosFsVolUnmount</a></i>( )</b>. Instead use <b><i><a href="./ioLib.html#ioctl">ioctl</a></i>( )</b> with FIOUNMOUNT whichaccesses the volume information via the file descriptor.<p></blockquote><h4>RETURNS</h4><blockquote><p>OK or ERROR.<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./usrFd.html#top">usrFd</a></b>, <i>VxWorks Programmer's Guide: I/O System, Local File Systems, Intel i386/i486 Appendix</i></body></html>⌨️ 快捷键说明
