The habits of a software is undefined if a mutex is wrecked although even now owned by any threads, or possibly a thread terminates although owning a mutex. The mutex class satisfies all prerequisites of Mutex and StandardLayoutType.

If plan is std::launch::async
remaining - pointer to the object to put the remaining time on interruption. May very well be NULL, in which circumstance it is actually ignored
Mutual exclusion algorithms prevent many threads from concurrently accessing shared resources. This stops information races and presents assist for synchronization in between threads. Described in header
The best-degree functionality may well communicate its return price or an exception towards the caller by means of std::promise or by modifying shared variables (which can need synchronization, see std::mutex and std::atomic).
Even though the clock in use is std::chrono::steady_clock or A different monotonic clock, a system clock adjustment could induce a spurious wakeup.
Constant Clarification future_status::deferred The shared condition contains a deferred operate working with lazy analysis, so the result will likely be computed only when explicitly asked for future_status::Completely ready The result is ready future_status::timeout The timeout has expired [edit] Exceptions
This overload may very well be applied to ignore spurious awakenings whilst waiting for a selected affliction to become accurate.
This operate may block for extended than sleep_duration as a result of scheduling or resource rivalry delays.
If the future is the results of a contact to std::async that made use of lazy evaluation, this functionality returns right away without the need of waiting around.
A semaphore is a light-weight synchronization primitive utilized to constrain concurrent entry to a shared source. When possibly would suffice, a semaphore could be additional efficient than a ailment variable. Defined in header

In case the purpose file returns a Stages of sleep price or throws an exception, it can be saved from the shared point out obtainable from the std::upcoming that std::async returns into the caller. [edit] Deferred invocation
