TIFFWarning(3T)   Image Format Library C++ Reference Manual    TIFFWarning(3T)



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,

     valist 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.
