33.3.5.3 Member functions [stopsource.mem]

void swap(stop_source& rhs) noexcept;

Effects: Equivalent to: stop-state.swap(rhs.stop-state);

🔗

stop_token get_token() const noexcept;

Returns: stop_token() if stop_possible() is false; otherwise a new associated stop_token object; i.e., its stop-state member is equal to the stop-state member of *this.

🔗

bool stop_possible() const noexcept;

Returns: stop-state != nullptr.

🔗

bool stop_requested() const noexcept;

Returns: true if stop-state refers to a stop state that has received a stop request; otherwise, false.

🔗

bool request_stop() noexcept;

Effects: Executes a stop request operation ([stoptoken.concepts]) on the associated stop state, if any.
