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