TIFFError
=========
Synopsis
--------
.. highlight:: c
::
#include <tiffio.h>
#include <stdarg.h>
.. c:function:: void TIFFError(const char * module, const char * fmt, ...)
.. c:type:: void (*TIFFErrorHandler)(const char * module, const char* fmt, va_list ap)
.. c:function:: TIFFErrorHandler TIFFSetErrorHandler(TIFFErrorHandler handler)
Description
-----------
:c:func:`TIFFError` invokes the library-wide error handling function to (normally) write an error
message to ``stderr``. The *fmt* parameter is a :c:func:`printf` 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
:c:func:`TIFFSetErrorHandler` to override the default error handler.
A :c:macro:`NULL` (0) error handling function may be installed to suppress error messages.
Return values
-------------
:c:func:`TIFFSetErrorHandler` returns a reference to the previous error handling function.
