TIFFWarning(3TIFF)                                          TIFFWarning(3TIFF)



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
       (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.
