The function
barrier-unblock
unblocks the barrier
barrier
, potentially disabling it, resetting its count or killing the waiting processes.
Without keyword arguments,
barrier-unblock
unblocks the barrier, which means that any thread that is waiting on the barrier wakes and returns from barrier-wait, and the arriver count is reset to 0.
If
disable
is true, or if
disable
is not passed and the barrier was made with
disable-on-unblock
true, then
barrier-unblock
also disables the barrier, so any further calls to barrier-wait return
nil
immediately.
If
reset-count
is true, it must be valid count (a positive fixnum or
t
), and
barrier-unblock
sets the count of the barrier to this value.
If
kill-waiting
is true, instead of waking up the waiting threads,
barrier-unblock
kills them (by process-kill).
