std::filesystem::begin(recursive_directory_iterator), std::filesystem::end(recursive_directory_iterator) - cppreference.com (original) (raw)

1. Returns iter unchanged.

These non-member functions enable the use of recursive_directory_iterators with range-based for loops and make recursive_directory_iterator a range type(since C++20).

[edit] Parameters

[edit] Return value

1. iter unchanged.

2. End iterator (default-constructed recursive_directory_iterator).

[edit] Example

#include #include #include #include namespace fs = std::filesystem;   int main() { fs::current_path(fs::temp_directory_path()); fs::create_directories("sandbox/a/b"); std::ofstream("sandbox/file1.txt"); fs::create_symlink("a", "sandbox/syma");   std::cout << "Print dir structure using OS specific command 'tree':\n"; std::system("tree --noreport sandbox");   std::cout << "\nPrint dir structure using directory iterator:\n"; for (auto& p : fs::recursive_directory_iterator("sandbox")) std::cout << p << '\n';   fs::remove_all("sandbox"); }

Possible output:

Print dir structure using OS specific command 'tree': sandbox ├── a │   └── b ├── file1.txt └── syma -> a   Print dir structure using directory iterator: "sandbox/syma" "sandbox/file1.txt" "sandbox/a" "sandbox/a/b"
