61 * An application finds out how many objects an SES instance
62 * is managing by performing a SESIOC_GETNOBJ operation. It then
63 * performs a SESIOC_GETOBJMAP to get the map that contains the
64 * object identifiers for all objects (see ses_object below).
65 * This information is static.
66 *
67 * The application may perform SESIOC_GETOBJSTAT operations to retrieve
68 * status on an object (see the ses_objstat structure below), SESIOC_SETOBJSTAT
69 * operations to set status for an object.
70 *
71 * Similarly overall enclosure status me be fetched or set via
72 * SESIOC_GETENCSTAT or SESIOC_SETENCSTAT operations (see ses_encstat below).
73 *
74 * Readers should note that there is nothing that requires either a set
75 * or a clear operation to actually latch and do anything in the target.
76 *
77 * A SESIOC_INIT operation causes the enclosure to be initialized.
