TIFFError(3tiff)

NAME

       TIFFError, TIFFSetErrorHandler - library error handling interface

SYNOPSIS

       #include <tiffio.h>

       void TIFFError(const char *module, const char *fmt, ...)

       #include <stdarg.h>

       typedef  void  (*TIFFErrorHandler)(const char *module, const char *fmt,
       va_list ap);
       TIFFErrorHandler TIFFSetErrorHandler(TIFFErrorHandler handler);

DESCRIPTION

       TIFFError invokes the library-wide error  handling  function  to  (nor-
       mally)  write  an  error message to the stderr.  The fmt parameter is a
       printf(3S) format string, and any number arguments can be supplied. The
       module  parameter, if non-zero, is printed before the message; it typi-
       cally is used to identify the software module  in  which  an  error  is
       detected.

       Applications  that  desire  to capture control in the event of an error
       should use TIFFSetErrorHandler to override the default  error  handler.
       A  NULL  (0) error handling function may be installed to suppress error
       messages.

RETURN VALUES

       TIFFSetErrorHandler returns a reference to the previous error  handling
       function.
