Functions
FCPPT_DETAIL_SYMBOL fcppt::io::ostream &	cerr ()
	Returns either std::cerr or std::wcerr, depending on fcppt::char_type.
FCPPT_DETAIL_SYMBOL fcppt::io::istream &	cin ()
	Returns either std::cin or std::wcin, depending on fcppt::char_type.
FCPPT_DETAIL_SYMBOL fcppt::io::ostream &	clog ()
	Returns either std::clog or std::wclog, depending on fcppt::char_type.
FCPPT_DETAIL_SYMBOL fcppt::io::ostream &	cout ()
	Returns either std::cout or std::wcout, depending on fcppt::char_type.
template<typename Ch, typename Traits, typename Type>
std::basic_istream< Ch, Traits > &	expect (std::basic_istream< Ch, Traits > &_stream, Type const &_value)
	Fails a stream if it does not read the expected value.
template<typename Type, typename Ch, typename Traits>
fcppt::optional::object< Type >	extract (std::basic_istream< Ch, Traits > &_stream)
	Reads a value from a stream, returning an optional.
template<typename Ch, typename Traits>
fcppt::optional::object< Ch >	get (std::basic_istream< Ch, Traits > &_stream)
	Gets a character from a stream.
template<typename Ch, typename Traits>
fcppt::optional::object< std::string >	narrow_string (std::basic_ios< Ch, Traits > const &_ios, std::basic_string_view< Ch, Traits > const _string)
	Uses narrow on every character.Calls fcppt::io::narrow_string_locale using the locale from _ios.
template<typename Ch, typename Traits>
fcppt::optional::object< std::string >	narrow_string_locale (std::basic_string_view< Ch, Traits > const _string, std::locale const &_locale)
	Uses narrow on every character.Let _string = c_1 ... c_n and d_i = narrow(c_i,0) for i = 1,...,n, where narrow is the function from std::ctype<Ch>. Then this function returns the string d_1, ..., d_n if and only if d_i != 0 for i = 1,...,n.
template<typename Ch, typename Traits>
fcppt::optional::object< Ch >	peek (std::basic_istream< Ch, Traits > &_stream)
	Peeks at a character from a stream.
template<typename Type> requires std::is_arithmetic_v<Type>
fcppt::optional::object< Type >	read (std::istream &_stream, std::endian const _format)
	Reads an object of arithmetic type from a stream.
FCPPT_DETAIL_SYMBOL fcppt::io::optional_buffer	read_chars (std::istream &stream, std::size_t count)
	Reads a number of chars.
template<typename Ch, typename Traits>
fcppt::optional::object< std::basic_string< Ch, Traits > >	stream_to_string (std::basic_istream< Ch, Traits > &_input)
	Reads the contents of a stream into a string.
fcppt::io::detail::widen_string	widen_string (std::string _string)
	Creates a string that outputs each character by widening.
template<typename Type> requires std::is_arithmetic_v<Type>
void	write (std::ostream &_stream, Type const &_value, std::endian const _format)
	Writes an object of arithmetic type to a stream.
FCPPT_DETAIL_SYMBOL bool	write_chars (std::ostream &stream, char const *data, std::size_t count)
	Writes a number of chars.
