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