74 *
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.
