   Starting_Address : in     RTEMS.Address;
   Length           : in     RTEMS.Unsigned32;
   Result           :    out RTEMS.Status_Codes
);

DIRECTIVE STATUS CODES:

RTEMS.SUCCESSFUL - region extended successfully
RTEMS.INVALID_ADDRESS - starting_address is NULL
RTEMS.INVALID_ID - invalid region id
RTEMS.INVALID_ADDRESS - invalid address of area to add

DESCRIPTION:

This directive adds the memory which starts at starting_address for length bytes to the region specified by id.

NOTES:

This directive will not cause the calling task to be preempted.

The calling task does not have to be the task that created the region. Any local task that knows the region id can extend the region.
