protected: basic_streambuf(const basic_streambuf& rhs); | (2) | (since C++11) |
basic_streambuf
object, initializes the six pointer members (eback()
,gptr()
,egptr()
,pbase()
,pptr()
, andepptr()
) to null pointer values, and the locale member tostd::locale(), a copy of the global C++ locale at the time of construction.Both constructors are protected, and are only called by the concrete streambuf classes, such asstd::basic_filebuf,std::basic_stringbuf, orstd::strstreambuf.

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