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