  PURPOSE : If an error is stored in the errorlist, this function
            copies information on the error into the function parameter.
            This information is made of error number, error-union type,
            ccd_id for the faulty element and the address of this
            element in the C-structure of the decoded message. 
            If no error occured this function returns 0.
