RTEMS C User's Guide

rtems_status_code rtems_region_extend(
  rtems_id            id,
  void               *starting_address,
  rtems_unsigned32    length
);

RTEMS_SUCCESSFUL - region extended successfully
RTEMS_INVALID_ID - invalid region id
RTEMS_INVALID_ADDRESS - invalid address of area to add

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

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.
