std::basic_ios::init

protected:
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:

Element	Value
`rdbuf()`	`sb`
`tie()`	`NULL`
`rdstate()`	`goodbit` if `sb` is not `NULL`, otherwise `badbit`
`exceptions()`	`goodbit`
`flags()`	`skipws \| dec`
`width()`	`0`
`precision()`	`6`
`fill()`	`widen(' ')`
`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.

Parameters

stream buffer to associate to
