* An application finds out how many objects an SES instance

* performs a SESIOC_GETOBJMAP to get the map that contains the
* object identifiers for all objects (see ses_object below).
* This information is static.
*
* The application may perform SESIOC_GETOBJSTAT operations to retrieve
* status on an object (see the ses_objstat structure below), SESIOC_SETOBJSTAT
* operations to set status for an object.
*
* Similarly overall enclosure status me be fetched or set via
* SESIOC_GETENCSTAT or SESIOC_SETENCSTAT operations (see ses_encstat 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.
