basic_ios::rdbuf
basic_streambuf<Elem, Tr> *rdbuf() const;
basic_streambuf<Elem, Tr> *rdbuf(basic_streambuf<Elem, Tr> *strbuf);
The first member function returns the stored stream buffer pointer.
The second member function stores strbuf in the stored stream buffer pointer and returns the
previously stored value.
basic_ios::rdstate
iostate rdstate() const;
The member function returns the stored stream state information.
basic_ios::setstate
void setstate(iostate state);
The member function effectively calls clear(state | rdstate()).
basic_ios::tie
basic_ostream<Elem, Tr> *tie() const;
basic_ostream<Elem, Tr> *tie(basic_ostream<Elem, Tr> *newtie);
The first member function returns the stored tie pointer. The second member function stores newtie
in the tie pointer and returns its previous stored value.
basic_ios::traits_type
typedef Tr traits_type;
The type is a synonym for the template parameter Tr.
basic_ios::widen
char_type widen(char ch);
The member function returns use_facet< ctype<Elem> >( getloc()). widen(ch).
boolalpha
ios_base& boolalpha(ios_base& iosbase);
The manipulator effectively calls iosbase.setf(ios_base:: boolalpha), then returns
str.
