std::basic_iostream::basic_iostream

(1) inititalization constructor

Assigns initial values to the components of its base classes by calling the constructors its base classes basic_istream and basic_ostream with sb as argument.
Notice that this calls member basic_ios::init twice.

(2) copy constructor (deleted)

Deleted: no copy constructor.

(3) move constructor (protected)

Acquires the contents of x, except its associated stream buffer: It calls basic_istream's constructor with move(x) as argument, transferring some of x's internal components to the object: x is left with a gcount value of zero, not tied, and with its associated stream buffer unchanged (all other components of x are in an unspecified but valid state after the call).

Parameters

sb

pointer to a basic_streambuf object with the same template parameters as the basic_iostream object.
char_type and traits_type are member types defined as aliases of the first and second class template parameters, respectively (see basic_iostream types).

x

Another basic_iostream of the same type (with the same class template arguments charT and traits).
