<p><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.</p>
|
|
|
|
|
<!-- INDENTATION -->
|
|
|
|
|
<p>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.</p>
