TIFFWarning(3TIFF)                                          TIFFWarning(3TIFF)

NAME
       TIFFWarning, TIFFSetWarningHandler - library warning interface

SYNOPSIS
       #include <tiffio.h>

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

       #include <stdarg.h>

       typedef void (*TIFFWarningHandler)(const char *module, const char *fmt,
       va_list ap);

       TIFFWarningHandler TIFFSetWarningHandler(TIFFWarningHandler handler);

DESCRIPTION
       TIFFWarning invokes the library-wide warning handler function to  (nor-
       mally)  write  a warning message to the stderr.  The fmt parameter is a
       printf(3S) format string, and any number arguments can be supplied. The
       module  parameter  is interpreted as a string that, if non-zero, should
       be printed before the message; it typically is  used  to  identify  the
       software module in which a warning is detected.

       Applications  that  desire to capture control in the event of a warning
       should use TIFFSetWarningHandler to override the default  warning  han-
       dler.  A NULL (0) warning handler function may be installed to suppress
       error messages.

RETURN VALUES
       TIFFSetWarningHandler returns a reference to the  previous  error  han-
       dling function.
