void init( std::basic_streambuf<CharT,Traits>* sb );
Sets the associated stream buffer to
sb and initializes the internal state.
The postconditions are as follows:
|flags()||skipws | dec|
|getloc()||a copy of the value returned by std::locale()|
This member function is protected: it is called by the constructors of the derived stream classes std::basic_istream and std::basic_ostream once the associated stream buffer is known. Until this function is called, every member function (other than the destructor) of the default-constructed std::basic_ios invokes undefined behavior. Note that
basic_ios is a virtual base class, and therefore its constructor is not called by the constructors of those directly derived classes, which is why two-stage initialization is necessary.
