<p><i>TIFFError</i> invokes the library-wide error handling
function to (normally) write an error 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, if non-zero,
is printed before the message; it typically is used to
identify the software module in which an error is
detected.</p>
<!-- INDENTATION -->
<p>Applications that desire to capture control in the event
of an error should use <i>TIFFSetErrorHandler</i> to
override the default error handler. A <small>NULL</small>
(0) error handling function may be installed to suppress
error messages.</p>
