Supplies a hint into the implementation to reschedule the execution of threads, letting other threads to run.
the connected thread completion synchronizes-with the effective return from the primary function that may be waiting around on the shared condition, or Using the return of the final functionality that releases the shared condition, whichever will come initial.
The normal endorses the clock tied to sleep_time be applied, by which scenario adjustments on the clock might be taken into consideration. Thus, the length of the block may very well be more or less than sleep_time - Clock::now() at enough time of the call, with regards to the way in the adjustment and whether it's honored through the implementation.
three) Registers *this for your length of the get in touch with, being notified if a stop ask for is built on stoken's connected halt-state; it really is then reminiscent of
The decision to std::async synchronizes with the decision to f, as well as the completion of file is sequenced before you make the shared state ready.
The actual sleep time could be extended than asked for mainly because it is rounded up to the timer granularity and because of scheduling and context switching overhead.
The standard endorses that a gentle clock is utilized to evaluate the period. If an implementation works by using a process clock alternatively, the wait around time can also be sensitive to clock adjustments.
The function also may perhaps block right up until soon after sleep_time is attained due to system scheduling or source contention delays.
This purpose might block for longer than timeout_duration resulting from scheduling or source rivalry delays.
If the long run is the results of a get in touch with to std::async that made use of lazy evaluation, this purpose returns instantly devoid of waiting.
A semaphore is a light-weight synchronization primitive used to constrain concurrent entry to a shared useful resource. When either would suffice, a semaphore might be extra efficient than the usual condition variable. Outlined in header

This enables the functionality to check if quit is asked for all through its execution, and return if it has.
In the event the std::foreseeable future attained from std::async is not moved from or bound to a reference, the destructor on the std::long run will Stages of sleep block at the conclusion of the full expression until finally the asynchronous Procedure completes, fundamentally earning code like the next synchronous:
