            <parameter>label</parameter> is the address of a string that will be used to store the object label.

            <parameter>length</parameter> contains the address of a variable which will receive the the number of characters in the object label.
            If <parameter>length</parameter> is NULL, then it is ignored and no data is written. Likewise, if <parameter>label</parameter>
            is NULL, or if <parameter>bufSize</parameter> is zero then no data is written to <parameter>label</parameter>.
