template<class T>
inline void carb::thread::futex::wake(std::atomic<T> &val, unsigned count, unsigned maxCount = unsigned(INT_MAX)) Wakes threads that are waiting in one of the
futex
wait functions.Note
To wake all threads waiting on
val
, use wake_all().- Parameters
val – The same value that was passed to wait(), wait_for() or wait_until().
count – The number of threads to wake. To wake all threads, use wake_all().
maxCount – An optimization for Windows that specifies the total number of threads that are waiting on
addr
. Ifcount
is greater-than-or-equal-tomaxCount
then a specific API call that wakes all threads is used. Ignored on Linux.
