Constructs an object of type basic_istream.

explicit basic_istream(
    basic_streambuf<Elem, Tr> *_Strbuf,
    bool _Isstd = false



An object of type basic_streambuf.


true if this is a standard stream; otherwise, false.

The constructor initializes the base class by calling init(_Strbuf). It also stores zero in the extraction count. For more information on this extraction count, see the Remarks section of the basic_istream Class overview topic.

See the example for basic_ifstream::basic_ifstream to learn more about input streams.
