NAME

     TIFFWarning, TIFFSetWarningHandler - library warning  inter-
     face

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  func-
     tion  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  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 handler.  A NULL (0) warning  handler  func-
     tion may be installed to suppress error messages.

RETURN VALUES

     TIFFSetWarningHandler returns a reference  to  the  previous
     error handling function.
