61<p><i>TIFFError</i> invokes the library-wide error handling
62function to (normally) write an error message to the
63<b>stderr</b>. The <i>fmt</i> parameter is a
64<i>printf</i>(3S) format string, and any number arguments
65can be supplied. The <i>module</i> parameter, if non-zero,
66is printed before the message; it typically is used to
67identify the software module in which an error is
68detected.</p>
69<!-- INDENTATION -->
70<p>Applications that desire to capture control in the event
71of an error should use <i>TIFFSetErrorHandler</i> to
72override the default error handler. A <small>NULL</small>
73(0) error handling function may be installed to suppress
74error messages.</p>
