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.

[edit] Parameters

os - stream to perform output on

[edit] Exceptions

May throw implementation-defined exceptions.

[edit] Example

#include <iostream>
#include <filesystem>
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"
