Derives from kdu_message
[Declared in "../coresys/common/kdu_messaging.h"]
Objects of this class are used in a similar manner to kdu_error objects, except that the destructor does not terminate the currently executing process. Note, however, that even warning handlers may conceivable throw exceptions or terminate the process themselves. The warning handler is configured using kdu_customize_warnings. For this reason, kdu_warning objects should never be created on the heap.
