Module `CCThread.Barrier`

type t: Barrier, used to synchronize threads

val create : unit -> t: Create a barrier.

val reset : t -> unit: Reset to initial (non-triggered) state.

val wait : t -> unit: wait b waits for barrier b to be activated by activate b. All threads calling this wait until activate b is called. If b is already activated, wait b does nothing.

val activate : t -> unit: activate b unblocks all threads that were waiting on b.

val activated : t -> bool: activated b returns true iff activate b was called, and reset b was not called since. In other words, activated b = true means wait b will not block.
