#### io_context::stopped

Determine whether the `io_context` object has been stopped.

    bool stopped() const;

This function is used to determine whether an `io_context` object has been stopped, either through an explicit call to `stop()`, or due to running out of work. When an `io_context` object is stopped, calls to `run()`, `run_one()`, `poll()` or `poll_one()` will return immediately without invoking any handlers.

###### Return Value

`true` if the `io_context` object is stopped, otherwise `false`.
