If the fileindicated is a TSFS file, this routine has the same result as uploading to ahost file using other methods, allowing it to replace evtRecv. The file can becreated anywhere, however, and event data can be kept on the target ifdesired.<p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./wvSockUploadPathLib.html#top">wvSockUploadPathLib</a></b>, <b><a href="./wvTsfsUploadPathLib.html#top">wvTsfsUploadPathLib</a></b><hr><a name="fileUploadPathLibInit"></a><p align=right><a href="rtnIndex.htm"><i>OS Libraries : Routines</i></a></p></blockquote><h1>fileUploadPathLibInit( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong>fileUploadPathLibInit( )</strong> - initialize the <b><a href="./wvFileUploadPathLib.html#top">wvFileUploadPathLib</a></b> library (Windview)</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS fileUploadPathLibInit (void)</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine initializes the library by pulling in the routines in this file for use with WindView.
