X::native_handle_type

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

a.конструкция(b;

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

a.destroy(b);

From IoObjectService requirements. Implicitly cancels asynchronous operations, as if by calling a.close(b, ec).

a.move_construct(b, c);

Из требований IoObjectService. Базовое представление происходит от c до 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

const X& u = a;
const X::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.
