  70  * performs a SESIOC_GETOBJMAP to get the map that contains the
  71  * object identifiers for all objects (see ses_object below).
  72  * This information is static.
  73  *
  74  * The application may perform SESIOC_GETOBJSTAT operations to retrieve
  75  * status on an object (see the ses_objstat structure below), SESIOC_SETOBJSTAT
  76  * operations to set status for an object.
  77  *
  78  * Similarly overall enclosure status me be fetched or set via
  79  * SESIOC_GETENCSTAT or  SESIOC_SETENCSTAT operations (see ses_encstat below).

  81  * Readers should note that there is nothing that requires either a set
  82  * or a clear operation to actually latch and do anything in the target.
  83  *
  84  * A SESIOC_INIT operation causes the enclosure to be initialized.
