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