protected member function
<istream> <iostream>


copy (1)
iostream& operator= (const iostream&) = delete;
move (2)
iostream& operator= (iostream&& rhs);
Move assignment
Exchanges all internal members between rhs and *this, except the pointer to the associated stream buffers: rdbuf shall return the same in both objects as before the call.

This is the same behavior as calling member iostream::swap.

Derived classes can call this function to implement move semantics.


Another istream object.

Return Value


Data races

Modifies both stream objects (*this and rhs).

Exception safety

No-throw guarantee: this member function never throws exceptions.
