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.
#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"
