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 (normally) 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 typically 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.
