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 pointer |
| rdstate() | goodbit if sb is not a null pointer, 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 (including the destructor) of the default-constructed std::basic_ios invokes undefined behavior. Note that basic_ios
