sleep Secrets
No synchronization is performed on *this by itself. Concurrently calling be a part of() on the exact same thread item from several threads constitutes an information race that ends in undefined behavior.

the affiliated thread completion synchronizes-Along with the prosperous return from the very first perform that's waiting on the shared point out, or While using the return of the final function that releases the shared condition, whichever comes first.
These parts are offered for good-grained atomic operations allowing for for lockless concurrent programming. Just about every atomic operation is indivisible with regards to every other atomic operation that consists of precisely the same object. Atomic objects are free of knowledge races.
Mutual exclusion algorithms reduce a number of threads from at the same time accessing shared assets. This helps prevent facts races and supplies support for synchronization Tips to improve your sleep routine amongst threads. Defined in header
Waits for The end result to become readily available. Blocks till specified timeout_duration has elapsed or The end result becomes offered, whichever will come very first. The return benefit identifies the state of the result.
Whether or not the clock in use is std::chrono::steady_clock or A different monotonic clock, a process clock adjustment may perhaps induce a spurious wakeup.
Whether or not notified beneath lock, overload (1) tends to make no guarantees about the point out with the affiliated predicate when returning on account of timeout.
In any scenario, the perform also may perhaps look forward to for a longer time than until immediately after abs_time is arrived at on account of scheduling or resource competition delays.
This function could block for for a longer period than timeout_duration because of scheduling or source rivalry delays.
duration and remaining might issue at a similar item, which simplifies re-jogging the purpose following a signal.

In the event the operate f returns a price or throws an exception, it really is stored within the shared state available throughout the std::potential that std::async returns for the caller. [edit] Deferred invocation
