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(TIFFWarningHan-
       dler handler);

DESCRIPTION
       TIFFWarning  invokes  the  library-wide  warning handler
       function to (normally) 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 typi-
       cally 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 over-
       ride the default warning handler.  A  NULL  (0)  warning
       handler function may be installed to suppress error mes-
       sages.

RETURN VALUES
       TIFFSetWarningHandler returns a reference to the  previ-
       ous error handling function.
