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