<X::native_handle_type>

The implementation-defined native representation of a descriptor. Must satisfy the requirements of CopyConstructible types (C++ Std, 20.1.3), and the requirements of Assignable types (C++ Std, 23.1).

a.construct(b);

From IoObjectService requirements.
post: !a.is_open(b).

a.destroy(b);

ИзТребования к IoObjectService. Неявно отменяет асинхронные операции, как бы звоня<a.close(b, ec)>.

a.move_construct(b, c);

ИзТребования к IoObjectService. Основное нативное представление перемещается из<c>в<b>

a.move_assign(b, ao, c);

From IoObjectService requirements. Implicitly cancels asynchronous operations associated with b, as if by calling a.close(b, ec). Then the underlying native representation is moved from c to b.

a.assign(b, n, ec);

error_code

pre: !a.is_open(b).
post: !!ec || a.is_open(b).

a.is_open(b);

bool

constX&u=a;
constX::implementation_type&v=b;
u.is_open(v);

bool

a.close(b, ec);

error_code

If a.is_open() is true, causes any outstanding asynchronous operations to complete as soon as possible. Handlers for cancelled operations shall be passed the error code error::operation_aborted.
