|
<p>The <strong>lstat64()</strong> function gets status information about a
|
|
specified file and places it in the area of memory pointed to by <em>buf</em>.
|
|
If the named file is a symbolic link, <strong>lstat64()</strong> returns
|
|
information about the symbolic link itself.</p>
|
|
|
|
<p>The information is returned in the <samp>stat64</samp> structure, referred
|
|
to by <em>buf</em>. For details on the <samp>stat64</samp> structure, see <a
|
|
href="stat64.htm">stat64()--Get File Information (Large File Enabled)</a>.</p>
|
|
|
|
<p>If the named file is not a symbolic link, <strong>lstat64()</strong> updates
|
|
the time-related fields before putting information in the <samp>stat64</samp>
|
|
structure.</p>
|
|
|
|
<p>For additional information about parameters, authorities required, and error
|
|
conditions, see <a href="lstat.htm">lstat()--Get File or Link
|
|
Information</a>.</p>
|
|
|
|
<p>See <a href="lstat64u.htm">QlgLstat64()--Get File or Link Information (Large
|
|

path</em> in any CCSID.</p>

<h3>Usage Notes</h3>
|
|
|
|
<ol type="1">
|
|
<li>When you develop in C-based languages, the prototypes for the 64-bit APIs
|
|
are normally hidden. To use the <strong>lstat64()</strong> API and the <samp>
|
|
struct stat64</samp> data type, you must compile the source with the
|
|
_LARGE_FILE_API defined.<br>
|
|
<br>
|
|
</li>
|
|
|
|
<li>All of the usage notes for <strong>lstat()</strong> apply to <strong>
|
|
lstat64()</strong>. See <a href="lstat.htm#HDRLSTAUSG">Usage Notes</a> in the
|
|
<strong>lstat()</strong> API.</li>
|
|
</ol>
