            <parameter>label</parameter> is the address of a string that will be used to label an object.
            <parameter>length</parameter> contains the number of characters in <parameter>label</parameter>.

            <parameter>label</parameter> contains a null-terminated string. If <parameter>label</parameter>
            is NULL, any debug label is effectively removed from the object.
