<i>TIFFWarning</i> 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.</td></table>
<table width="100%" border=0 rules="none" frame="void"
cols="2" cellspacing="0" cellpadding="0">
<tr valign="top" align="left">
<td width="10%"></td><td width="90%">
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.</td></table>
