std::coroutine_handle<Promise>:: from_address

static constexpr coroutine_handle from_address ( void * addr ) ;		(since C++20)

Creates a coroutine_handle from a null pointer value or an underlying address of another coroutine_handle . The underlying address of return value is addr .

The behavior is undefined if addr is neither a null pointer value nor an underlying address of a coroutine_handle . The behavior is also undefined if the addr is an underlying address of a std:: coroutine_handle < P1 > , where both Promise and P1 are not void , and P1 is different from Promise .

This function is not declared for specialization std:: coroutine_handle < std:: noop_coroutine_promise > .

Parameters

addr

-

underlying address to import

Return value

A std:: coroutine_handle < Promise > whose underlying address is addr .

Notes

If addr is not a null pointer value, it must be obtained from a prior call to address() on a coroutine_handle referring to some coroutine.
