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
