Module Await_blocking_futexSource

A handle to a linux futex for waiting on a trigger.

Returns a futex that may be used to wait on a trigger. A new futex may or may not be returned by each call to get.

Returns the current count of the futex.

Increments the count of the futex. Any call to wait on the same futex will check whether the associated trigger has been signaled before suspending the thread.

Wait until the count of the futex changes by suspending the thread until the futex is signaled, then return the current count.
