The function barrier-change-count
changes the count of the barrier barrier to new-count.
If barrier is enabled and the arriver count is less than new-count, this just sets the count of barrier to new-count and returns t
. Otherwise, it calls:
(barrier-unblock barrier :reset-count new-count)
and returns nil
.
