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> Applications that desire to capture control in the event of a warning should use <I>TIFFSetWarningHandler</I> to override the default warning handler.
