operator<< (std::filesystem::directory_entry)

From cppreference.com
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 .

Parameters

os - stream to perform output on
d - directory_entry to be inserted

Return value

os

Exceptions

May throw implementation-defined exceptions.

Example

#include <filesystem>
#include <iostream>
namespace fs = std::filesystem;
 
int main()
{
    const auto entries = {fs::directory_entry{fs::current_path()},
                          fs::directory_entry{fs::temp_directory_path()}};
 
    for (const fs::directory_entry& de : entries)
        std::cout << de << '\n';
}

Possible output:

"/home/猫"
"/tmp"
