<p>The <strong>QlgStatvfs64()</strong> function, like the <strong>
statvfs64()</strong> function, gets status information about the file system
that contains the file named by the <em>path</em> argument. The difference is
that the <strong>QlgStatvfs64()</strong> function takes a pointer to a
Qlg_Path_Name_T structure, while <strong>statvfs64()</strong> takes a pointer
to a character string.</p>
<p>Limited information on the <em>path</em> parameter is provided here. For
more information on the <em>path</em> parameter and for a discussion of other
parameters, authorities required, return values, and related information, see
<a href="statvfs.htm">statvfs()</a>--Get File System Information.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong><em>path</em></strong></dt>
<dd>(Input) A pointer to a Qlg_Path_Name_T structure that contains a path name
or a pointer to a path name of the file from which file system information is
required. For more information on the Qlg_Path_Name_T structure, see <a href=
"../apiref/pns.htm">Path name format</a>.</dd>
