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