<h2>QlgLstat()--Get File or Link Information (using NLS-enabled path name)</h2>
<div class="box" style="width: 80%;">
<br>
&nbsp;&nbsp;Syntax<br>
<pre>
#include &lt;sys/stat.h&gt;
int QlgLstat(Qlg_Path_Name_T <em>*path</em>,struct stat <em>*buf</em>);
</pre>
&nbsp;&nbsp;Service Program Name: QP0LLIB1<br>
<!-- iddvc RMBR -->
<br>
&nbsp;&nbsp;Default Public Authority: *USE<br>
<!-- iddvc RMBR -->
<br>
&nbsp;&nbsp;Threadsafe: Conditional; see Usage Notes for <a href="lstat.htm">lstat()</a>.<br>
<!-- iddvc RMBR -->
<br>
</div>
<p>The <strong>QlgLstat()</strong> function, like the <strong>lstat()</strong>
function, gets status information about a specified file and places it in the
area of memory pointed to by <em>buf</em>. The difference is that the <strong>
QlgLstat()</strong> function takes a pointer to a Qlg_Path_Name_T structure,
while <strong>lstat()</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="lstat.htm">lstat()</a>--Get File or Link 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. For more information on the
Qlg_Path_Name_T structure, see <a href="../apiref/pns.htm">Path name format</a>.</dd>
