TIFFError(3T)	  Image	Format Library C++ Reference Manual	 TIFFError(3T)

NAME    [Toc]    [Back]

     TIFFError,	TIFFSetErrorHandler - library error handling interface

SYNOPSIS    [Toc]    [Back]

     #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    [Toc]    [Back]

     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    [Toc]    [Back]

     TIFFSetErrorHandler returns a reference to	the previous error handling
     function.
