75  * An application finds out how many elements an enclosure instance
76  * is managing by performing a ENCIOC_GETNELM operation. It then
77  * performs a ENCIOC_GETELMMAP to get the map that contains the
78  * elment identifiers for all elements (see encioc_element_t below).
79  * This information is static.
80  *
81  * The application may perform ENCIOC_GETELMSTAT operations to retrieve
82  * status on an element (see the enc_elm_status_t structure below),
83  * ENCIOC_SETELMSTAT operations to set status for an element.
84  *
85  * Similarly, overall enclosure status me be fetched or set via
86  * ENCIOC_GETENCSTAT or  ENCIOC_SETENCSTAT operations (see encioc_enc_status_t
87  * below).
88  *
89  * Readers should note that there is nothing that requires either a set
90  * or a clear operation to actually latch and do anything in the target.
91  *
92  * A ENCIOC_INIT operation causes the enclosure to be initialized.
