std::basic_streambuf::basic_streambuf(3) C++ Standard Libary std::basic_streambuf::basic_streambuf(3)


std::basic_streambuf::basic_streambuf - std::basic_streambuf::basic_streambuf


protected: (1)
protected: (2) (since C++11)
basic_streambuf(const basic_streambuf& rhs);

1) Constructs the basic_streambuf object, initializes the six pointer members
(eback(), gptr(), egptr(), pbase(), pptr(), and epptr()) to null pointer values, and
the locale member to std::locale(), a copy of the global C++ locale at the time of
2) Constructs a copy of rhs, initializing the six pointers and the locale object
with the copies of the values held by rhs. Note that this is a shallow copy: the
pointers of the newly-constructed basic_streambuf are pointing into the same
character array as the pointers of rhs.

Both constructors are protected, and are only called by the concrete streambuf
classes, such as std::basic_filebuf, std::basic_stringbuf, or std::strstreambuf.


rhs - a streambuf object to copy


Until C++11, it was unspecified whether basic_streambuf or any of its derived
classes is CopyConstructible (LWG issue 421), and different C++ library
implementations provided different options.
