It packs files and directories into acompilable C file which can be built into VxWorks, and then mountedas a filesystem using <b><i><a href="../../vxworks/ref/memDrv.html#memDrv" >memDrv</a></i>( )</b>.<p><b><a href="./memdrvbuild.html#top">memdrvbuild</a></b> converts a directory hierarchy, and all of the filescontained within it, into a single C source file. The individualfiles are converted into C data arrays containing the contents of thefiles (which may be in any format), along with administrative datadescribing the names and sizes of the files. This constructed C filecan then be built into VxWorks in the normal way.<p>The generated C file also contains two function which can be called toregister or unregister all of the packed files and directories;they are mounted as a filesystem using <b><i><a href="../../vxworks/ref/memDrv.html#memDevCreateDir" >memDevCreateDir</a></i>( )</b>, and unmountedusing <b><i><a href="../../vxworks/ref/memDrv.html#memDevDelete" >memDevDelete</a></i>( )</b>. An include file is also generated, containinga declaration of this function.<p></blockquote><h4>USAGE</h4><blockquote><p>This utility is invoked as:<pre> memdrvbuild [ -o filebase ] [ -m mount ] directory</pre>where:<dl><dt>-o filebase<dd>The base name for the generated .c and .h files.Defaults to the name of the source directory.<p><dt>-m mount<dd>The name ("mount point") under which directory will be mountedon the target. Defaults to the name of the source directory.<p><dt>directory<dd>The source directory containing the files to be packedinto a <b><a href="../../vxworks/ref/memDrv.html#top" >memDrv</a></b> filesystem. </dl><p>The output C file contains two function, called memDrvAddFiles<i>mount</i>()and memDrvDeleteFiles<i>mount</i>(), where <i>mount</i> is the argument to the "-d"option, with non-alpha characters converted to <b>_</b>.This first function mounts the packed files using <b><i><a href="../../vxworks/ref/memDrv.html#memDevCreate" >memDevCreate</a></i>( )</b>. Thesecond function unmounts the packed files using <b><i><a href="../../vxworks/ref/memDrv.html#memDevDelete" >memDevDelete</a></i>( )</b>.The H file contains a declaration of those functions.<p>Each file will be mounted with the name "<i>mount</i>/<i>file</i>", where <i>file</i>is the pathname of the file below the indicated source directory.<p></blockquote><h4>EXAMPLE</h4><blockquote><p>Given a directory "docs", containing a number of files:<pre> memdrvbuild -m /mem -o memFiles docs</pre>will produce 2 files, <b>memFiles.c</b> and <b>memFiles.h</b>. <b>memFiles.c</b> willcontain the data for the packed files, plus two functions:<pre> STATUS memDrvAddFiles_mem (void); STATUS memDrvDeleteFiles_mem (void);</pre>When called, the first function will mount all of the contained files inthe filesystem under "/mem". For example, the file "<b>docs/fred.html</b>"would be mounted as "<b>/mem/fred.html</b>". The second function will unmountall of the contained files in the filesystem under "/mem".<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./memdrvbuild.html#top">memdrvbuild</a></b></body></html>⌨️ 快捷键说明
