template< class CharT, class Traits > std::basic_ostream<CharT,Traits>&     operator<<( std::basic_ostream<CharT,Traits>& os, const path& p );	(1)	(filesystem TS)
template< class CharT, class Traits > std::basic_istream<CharT,Traits>&     operator>>( std::basic_istream<CharT,Traits>& is, path& p );	(2)	(filesystem TS)

Performs stream input or output on the path p. std::quoted is used so that spaces are not truncation when later read by stream input operator.

Parameters

os	-	stream to perform output on
is	-	stream to perform input on
p	-	path to insert or extract

Return value

1) os

2) is

Exceptions

(none)

Possible implementation

First version
template< class CharT, class Traits > std::basic_ostream<CharT,Traits>& operator<<( std::basic_ostream<CharT,Traits>& os, const path& p ) { os << std::quoted(p.string<CharT,Traits>()); return os; }
Second version
template< class CharT, class Traits > std::basic_istream<CharT,Traits>& operator>>( std::basic_istream<CharT,Traits>& is, path& p ) { std::basic_string<CharT, Traits> t; is >> std::quoted(t); p = t; return is; }
