basic_streambuf();
protected:
basic_streambuf(const basic_streambuf& rhs);
(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 construction.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
[edit] Notes
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.
