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

template< class CharT, class Traits >
friend std::basic_ostream<CharT,Traits>&
    operator<<( std::basic_ostream<CharT,Traits>& os, const directory_entry& d );

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

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';
}
