NAME¶

std::basic_ios::basic_ios - std::basic_ios::basic_ios

Synopsis¶

protected: (1)
basic_ios();
public: (2)
explicit basic_ios( std::basic_streambuf<CharT, Traits>* sb );
private: (until C++11)
basic_ios( const basic_ios& ); (3)
public: (since C++11)
basic_ios( const basic_ios& ) = delete;

Constructs a new std::basic_ios object.

1) Default constructor. The internal state is not initialized. init() must be called
before the first use of the object or before destructor, otherwise the behavior is
undefined.
2) Initializes the internal state by calling init(sb). The associated stream buffer
is set to sb.
3) The copy constructor is
declared private and not defined
(until C++11)
explicitly defined as deleted
(since C++11): I/O streams are not CopyConstructible.

Parameters¶

sb - stream buffer to associate to
