protected member function
<istream> <iostream>
Swap internals
Exchanges all internal members between x and *this, except the pointer to the associated stream buffers: rdbuf shall return the same in both objects as before the call.
Internally, the function calls istream::swap.
Derived classes can call this function to implement custom swap functions.
Parameters
- x
- Another istream object.
Data races
Modifies both stream objects (*this and x).
Exception safety
No-throw guarantee: this member function never throws exceptions.
