RTEMS C User's Guide
A region can be removed from the system and returned
to RTEMS with the rtems_region_delete
directive. When a region is
deleted, its control block is returned to the RNCB free list. A
region with segments still allocated is not allowed to be
deleted. Any task attempting to do so will be returned an
error. As a result of this directive, all tasks blocked waiting
to obtain a segment from the region will be readied and returned
a status code which indicates that the region was deleted.
