61 <p><i>TIFFError</i> invokes the library-wide error handling
62 function to (normally) write an error message to the
63 <b>stderr</b>. The <i>fmt</i> parameter is a
64 <i>printf</i>(3S) format string, and any number arguments
65 can be supplied. The <i>module</i> parameter, if non-zero,
66 is printed before the message; it typically is used to
67 identify the software module in which an error is
70 <p>Applications that desire to capture control in the event
71 of an error should use <i>TIFFSetErrorHandler</i> to
