NAME
       TIFFWarning, TIFFSetWarningHandler - library warning interface

SYNOPSIS
       #include <tiffio.h>
       void TIFFWarning(const char* module, const char* fmt, ...)
       #include <stdargh.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 sup-
       press error messages.

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