std::filesystem::begin(directory_iterator), std::filesystem::end(directory_iterator) - cppreference.com (original) (raw)
| Defined in header | ||
|---|---|---|
| directory_iterator begin( directory_iterator iter ) noexcept; | (1) | (since C++17) |
| directory_iterator end( directory_iterator ) noexcept; | (2) | (since C++17) |
Returns iter unchanged.
Returns a default-constructed
, which serves as the end iterator. The argument is ignored.
These non-member functions enable the use of directory_iterators with range-based for loops and make directory_iterator a range type(since C++20).
[edit] Parameters
| iter | - | a directory_iterator |
|---|
[edit] Return value
iter unchanged.
End iterator (default-constructed
directory_iterator).
[edit] Example
#include #include #include namespace fs = std::filesystem; int main() { fs::create_directories("sandbox/a/b"); std::ofstream("sandbox/file1.txt"); std::ofstream("sandbox/file2.txt"); for (auto& p : fs::directory_iterator("sandbox")) std::cout << p << '\n'; fs::remove_all("sandbox"); }
Possible output:
"sandbox/a" "sandbox/file1.txt" "sandbox/file2.txt"
