     * performs a SESIOC_GETOBJMAP to get the map that contains the
     * object identifiers for all objects (see ses_object below).
     * This information is static.
     *
     * The application may perform SESIOC_GETOBJSTAT operations to retrieve
     * status on an object (see the ses_objstat structure below), SESIOC_SETOBJSTAT
     * operations to set status for an object.
     *
     * Similarly overall enclosure status me be fetched or set via
     * SESIOC_GETENCSTAT or  SESIOC_SETENCSTAT operations (see ses_encstat 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 SESIOC_INIT operation causes the enclosure to be initialized.
