<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b><i>TIFFWarning</i></b>
invokes the library-wide warning handler function to
(normally) write a warning message to the <b>stderr</b>. The
<i>fmt</i> parameter is a <i>printf</i>(3S) format string,
and any number arguments can be supplied. The <i>module</i>
parameter is interpreted as a string that, if non-zero,
should be printed before the message; it typically is used
to identify the software module in which a warning is
detected.</p>
<p style="margin-left:11%; margin-top: 1em">Applications
that desire to capture control in the event of a warning
should use <i>TIFFSetWarningHandler</i> to override the
default warning handler. A <small>NULL</small> (0) warning
handler function may be installed to suppress error
messages.</p>
<h2>RETURN VALUES
<a name="RETURN VALUES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><i>TIFFSetWarningHandler</i>
returns a reference to the previous error handling
function.</p>
