NAME

std::coroutine_handle::from_address - std::coroutine_handle::from_address

Synopsis

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 values

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.
