     * is managing by performing a ENCIOC_GETNELM operation. It then
     * performs a ENCIOC_GETELMMAP to get the map that contains the
     * elment identifiers for all elements (see encioc_element_t below).
     * This information is static.
     * 
     * The application may perform ENCIOC_GETELMSTAT operations to retrieve
     * status on an element (see the enc_elm_status_t structure below),
     * ENCIOC_SETELMSTAT operations to set status for an element.
     *
     * Similarly, overall enclosure status me be fetched or set via
     * ENCIOC_GETENCSTAT or  ENCIOC_SETENCSTAT operations (see encioc_enc_status_t
     * below).
     *
     * Readers should note that there is nothing that requires either a set
     * or a clear operation to actually latch and do anything in the target.
     *
     * A ENCIOC_INIT operation causes the enclosure to be initialized.
