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 suppress
       error messages.

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