<p style="margin-left:11%; margin-top: 1em">TIFFSetDirectory,
TIFFSetSubDirectory &minus; set the current directory for an
open <small>TIFF</small> file</p>

<h2>SYNOPSIS
<a name="SYNOPSIS"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em"><b>#include
&lt;tiffio.h&gt;</b></p>

<p style="margin-left:11%; margin-top: 1em"><b>int
TIFFSetDirectory(TIFF *</b><i>tif</i><b>, tdir_t</b>
<i>dirnum</i><b>) <br>
int TIFFSetSubDirectory(TIFF *</b><i>tif</i><b>,
uint64_t</b> <i>diroff</i><b>)</b></p>

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>



<p style="margin-left:11%; margin-top: 1em"><b><i>TIFFSetDirectory</i></b>
changes the current directory and reads its contents with
<i>TIFFReadDirectory</i>. The parameter <i>dirnum</i>
specifies the subfile/directory as an integer number, with
the first directory numbered zero.</p>


<p style="margin-left:11%; margin-top: 1em"><i>TIFFSetSubDirectory</i>
acts like <i>TIFFSetDirectory</i>, except the directory is
specified as a file offset instead of an index; this is
required for accessing subdirectories linked through a
<i>SubIFD</i> tag.</p>

<h2>RETURN VALUES
<a name="RETURN VALUES"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em">On successful
return 1 is returned. Otherwise, 0 is returned if
<i>dirnum</i> or <i>diroff</i> specifies a non-existent
directory, or if an error was encountered while reading the
directory&rsquo;s contents.</p>

<h2>DIAGNOSTICS
<a name="DIAGNOSTICS"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em">All error
messages are directed to the <i>TIFFError</i>(3TIFF)
routine.</p>

<p style="margin-left:11%; margin-top: 1em"><b>%s: Error
fetching directory count</b>. An error was encountered while
reading the &lsquo;&lsquo;directory count&rsquo;&rsquo;
field.</p>

<p style="margin-left:11%; margin-top: 1em"><b>%s: Error
fetching directory link</b>. An error was encountered while
reading the &lsquo;&lsquo;link value&rsquo;&rsquo; that
points to the next directory in a file.</p>
