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 (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
       function may be installed to suppress error messages.

RETURN VALUES

       TIFFSetWarningHandler returns a reference to the previous error handling function.
