Performs stream input or output on the pathp.std::quoted is used so that spaces do not cause truncation when later read by stream input operator.

These function templates are not visible to ordinaryunqualified orqualified lookup, and can only be found byargument-dependent lookup when std::filesystem::path is an associated class of the arguments. This prevents undesirable conversions in the presence of ausingnamespace std::filesystem;using-directive.

[edit]Possible implementation

template<class CharT,class Traits>friendstd::basic_ostream<CharT,Traits>&    operator<<(std::basic_ostream<CharT,Traits>& os,const path& p){    os<<std::quoted(p.string<CharT,Traits>());return os;}

template<class CharT,class Traits>friendstd::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;}

[edit]Example

#include <filesystem>#include <iostream> int main(){std::cout<<std::filesystem::current_path()<<'\n';std::cout<<std::filesystem::temp_directory_path()<<'\n';}
