No synchronization is carried out on *this itself. Concurrently contacting be a part of() on the identical thread object from many threads constitutes an information race that results in undefined actions.
A situation variable is usually a synchronization primitive that enables many threads to communicate with each other.
The sleep may perhaps resume before if a sign that's not disregarded is received. In this kind of case, if remaining isn't NULL, the remaining time duration is stored into the thing pointed to by remaining.
The regular library provides amenities to get values which can be returned and to capture exceptions that happen to be thrown by asynchronous duties (i.e. functions released in individual threads). These values are communicated within a shared state, during which the asynchronous job may produce its return worth or shop an exception, and which can be examined, waited for, and normally manipulated by other threads that maintain instances of std::upcoming or std::shared_future that reference that shared condition. Defined in header
Provides a touch towards the implementation to reschedule the execution of threads, allowing for Tips to improve your sleep routine other threads to run.
Waits for The end result to become accessible. Blocks right up until specified timeout_duration has elapsed or The end result becomes obtainable, whichever arrives initially. The return benefit identifies the state of the result.
blocks the current thread till the condition variable is awakened or until specified time point has been arrived at (general public member functionality) [edit] Indigenous take care of
Constant Rationalization future_status::deferred The shared point out is made up of a deferred operate making use of lazy evaluation, so The end result are going to be computed only when explicitly asked for future_status::Prepared The result is ready future_status::timeout The timeout has expired [edit] Exceptions
This overload may be applied to ignore spurious awakenings while watching for a particular condition to be accurate.
This operate may block for for a longer period than sleep_duration on account of scheduling or resource rivalry delays.
duration and remaining may well level at a similar object, which simplifies re-running the purpose after a sign.
A semaphore is a lightweight synchronization primitive utilized to constrain concurrent access to a shared source. When possibly would suffice, a semaphore may be far more successful than the usual condition variable. Described in header

When the perform f returns a value or throws an exception, it really is stored inside the shared condition available with the std::potential that std::async returns for the caller. [edit] Deferred invocation
