Transfers all internal members of x to
x is left in an unspecified but valid state, except that it is not tied (tie returns always a null pointer) and its associated stream buffer is unchanged (rdbuf returns the same as before the call).
Derived classes can call this function to implement move semantics.
Concurrent access to any of these stream objects may cause data races.

std::basic_ios::move
void move (basic_ios& x);void move (basic_ios&& x);
Move internals
*this, except the associated stream buffer (rdbuf returns a null pointer after the call).x is left in an unspecified but valid state, except that it is not tied (tie returns always a null pointer) and its associated stream buffer is unchanged (rdbuf returns the same as before the call).
Derived classes can call this function to implement move semantics.
Parameters
- x
- Stream object whose members are moved to *this.
Return Value
noneData races
Modifies both stream objects (*this and x).Concurrent access to any of these stream objects may cause data races.
Exception safety
Basic guarantee: if an exception is thrown, both streams are in a valid state.See also
- basic_ios::swap
