void unhandled_exception();
(since C++23)

Let x be some generator object.

If a handle referring to the coroutine whose promise object is *this is at the top of *active_ of x:

  • If the handle referring to the coroutine whose promise object is *this is the only element of x.*active_, equivalent to throw.
  • Otherwise, assigns std::current_exception() to except_.
  • Otherwise, the behavior is undefined.

Parameters

(none)

Return value

(none)
