template< class CharT, class Traits >
friend std::basic_ostream<CharT,Traits>&
operator<<( std::basic_ostream<CharT,Traits>& os, const directory_entry& d );
| (since C++17) |
Performs stream output on the directory entry d. Equivalent to return os << d.path();.
This function template is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::filesystem::directory_entry is an associated class of the arguments. This prevents undesirable conversions in the presence of a using namespace std::filesystem; using-directive.
| os | - | stream to perform output on |
| d | - | directory_entry to be inserted |
os.
May throw implementation-defined exceptions.

};
for (const fs::directory_entry& de : entries) {
std::cout << de << '\n';
}
}Possible output:
"/home/猫" "/tmp"
