63<p><i>TIFFWarning</i> invokes the library-wide warning
64handler function to (normally) write a warning message to
65the <b>stderr</b>. The <i>fmt</i> parameter is a
66<i>printf</i>(3S) format string, and any number arguments
67can be supplied. The <i>module</i> parameter is interpreted
68as a string that, if non-zero, should be printed before the
69message; it typically is used to identify the software
70module in which a warning is detected.</p>
71<!-- INDENTATION -->
72<p>Applications that desire to capture control in the event
73of a warning should use <i>TIFFSetWarningHandler</i> to
74override the default warning handler. A <small>NULL</small>
75(0) warning handler function may be installed to suppress
76error messages.</p>
