DOFException DOFOperation_GetException ( const DOFOperation  op ) Get the exception associated with a completed operation, if any. This reports the same exception that is normally delivered to the operation's Complete callback, if any. If the operation is not yet complete, this will return NULL. Lifecycle The data returned is owned by the DOFOperation and is only valid as long as the DOFOperation remains valid. It must not be destroyed individually. If the exception is needed for longer, use DOFException_Copy to obtain a separate copy of the exception. Parameters op The Operation. Must not be NULL. Returns The exception associated with the operation, if any. NULL is returned if there is no exception. See Also DOFOperation_IsComplete
