std::stop_s...equest_stop(3) C++ Standard Libary std::stop_s...equest_stop(3) NAME std::stop_source::request_stop - std::stop_source::request_stop Synopsis bool request_stop() noexcept; (since C++20) Issues a stop request to the stop-state, if the stop_source object has a stop-state and it has not yet already had stop requested. The determination is made atomically, and if stop was requested, the stop-state is atomically updated to avoid race conditions, such that: * stop_requested() and stop_possible() can be concurrently invoked on other stop_tokens and stop_sources of the same stop-state; * request_stop() can be concurrently invoked on other stop_source objects, and only one will actually perform the stop request. However, see the Notes section. Parameters (none) Return value true if the stop_source object has a stop-state and this invocation made a stop request, otherwise false. Postconditions stop_possible() is false or stop_requested() is true. Notes If the request_stop() does issue a stop request (i.e., returns true), then any stop_callbacks registered for the same associated stop-state will be invoked synchronously, on the same thread request_stop() is issued on. If an invocation of a callback exits via an exception, std::terminate is called. If the stop_source object has a stop-state but a stop request has already been made, this function returns false. However there is no guarantee that an- other stop_source object which has just (successfully) requested stop is not still in the middle of invoking a stop_callback function. If the request_stop() does issue a stop request (i.e., returns true), then all condition variables of base type std::condition_variable_any regis- tered with an interruptible wait for stop_tokens associated with the stop_source's stop-state will be notified.
