RTEMS C User's Guide
The rtems_barrier_delete directive removes a barrier
from the system and frees its control block. A barrier can be
deleted by any local task that knows the barrier's ID. As a
result of this directive, all tasks blocked waiting for the
barrier to be released, will be readied and returned a status code which
indicates that the barrier was deleted. Any subsequent
references to the barrier's name and ID are invalid.
