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.
