.SH NAME

\f2basic_iostream\fP

\ - Assists in formatting and interpreting sequences of characters controlled by a stream buffer.



.SH  SYNOPSIS


.br
#include <istream>
.br
template<class charT, class traits = char_traits<charT> >
.br
class basic_iostream 
.br
: public basic_istream<charT, traits>,
.br
public basic_ostream<charT, traits>



.SH  DESCRIPTION


The class basic_iostream inherits a number of functions from classes basic_ostream<charT,_traits> and basic_istream<charT,_traits>. They assist in formatting and interpreting sequences of characters controlled by a stream buffer. Two groups of functions share common properties, the formatted functions and the unformatted functions.
