std::inplace_stop_token::stop_possible

bool stop_possible() const noexcept;

Checks if the inplace_stop_token object has associated stop-state, and that state either has already had a stop requested or it has associated std::stop_source object(s).

Equivalent to return this->/*stop_source_*/ != nullptr;.

A default constructed inplace_stop_token has no associated stop-state, and thus cannot be stopped; the associated stop-state for which no std::stop_source object(s) exist can also not be stopped if such a request has not already been made.

If the call does not happens strongly before the end of the storage duration of the associated std::inplace_stop_source object (if any), the behavior is implementation-defined.

Return value

false if the inplace_stop_token object has no associated stop-state, or it did not yet receive a stop request and there are no associated std::stop_source object(s); true otherwise.

Notes

If the inplace_stop_token object has associated stop-state and a stop request has already been made, this function still returns true.
