32.3.9.2 Constructors [stopsource.inplace.cons]

🔗
constexpr inplace_stop_source() noexcept;
1
#
Effects: Initializes a new stop state inside *this.
2
#
Postconditions: stop_requested() is false.

32.3.9.3 Member functions [stopsource.inplace.mem]

🔗
constexpr inplace_stop_token get_token() const noexcept;
1
#
Returns: A new associated inplace_stop_token object whose stop-source member is equal to this.
🔗
bool stop_requested() const noexcept;
2
#
Returns: true if the stop state inside *this has received a stop request; otherwise, false.
🔗
bool request_stop() noexcept;
3
#
Effects: Executes a stop request operation ([stoptoken.concepts]).
4
#
Postconditions: stop_requested() is true.
