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.
