72 *
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.
