- *Effects:* Constructs an object of class `basic_istream`, initializing
8
- the base class subobject with
9
- `basic_ios::init(sb)` ([[basic.ios.cons]]).
10
 
11
- *Postconditions:* `gcount() == 0`.
12
 
13
  ``` cpp
14
  basic_istream(basic_istream&& rhs);
15
  ```
16
 
17
- *Effects:* Move constructs from the rvalue `rhs`. This is accomplished
18
- by default constructing the base class, copying the `gcount()` from
19
- `rhs`, calling `basic_ios<charT, traits>::move(rhs)` to initialize the
20
- base class, and setting the `gcount()` for `rhs` to 0.

22
  ``` cpp
23
  virtual ~basic_istream();

  ```
25
 
26
- *Effects:* Destroys an object of class `basic_istream`.
27
-
28
  *Remarks:* Does not perform any operations of `rdbuf()`.
